Re: Fw: RDi 9.5 "not responding" -- WDSCI-L

These thread deadlock situations that involve the user interface thread are
fatal. No user interface actions can happen because the user interface
thread is hung waiting on a lock it will never get.
Of course we should never let this happen, and I did specifically code for
this situation but it was really subtle where I happened to place the lock
in an anonymous inner class and that cause it to be a different lock and
that got us into the classic dining philosophers deadlock. I was staring
at the code for hours and had to try to explain it to someone else before I
finally clued in :-) It was in the live RPG code, so unchecking that would
work around the problem.
BTW, this bug has been in there since RDi 9.1.1.1
Planning to release a test fix soon.

It would be nice if RDi had a pop-up to inform the user that there is a
lock and also allow backing out of the operation, if desired.

I am going to apply the Test fix pack to my new laptop. So, going

forward, there should be no way can blame it on a slow PC.<LOL>

Should only take me 10-minutes. Just did a brand new install of RDi

9.5.0.1 last night.

I also need to change my eclipse.ini to use "java.exe" instead of

"javaw.exe" for debug purposes.

I appreciate Mike pointing to me about "locks"... I had a lock editing a

display-file, and I had the screen up on the 5250 session. Back out on
that, and RDI starting responding again immediately!

That was understandable. But, when I only have a brand new code in

library and RDI 9.5 locks up, that is strange to me...

I want to go forward with my brand new install, after I re-apply the test

patch from 2015-10-27, if I remember correctly.

Edmund/Alex,

I got the "Not Responding" again...

I was duplicating code using ALT+C (Copy-Paste) and changing the

statement.

When it locked up. I think I used Code-Assist to look up a variable name.

I think It locked up on the paste operation with the "Alt+C".<frown>

So, this time I did the Ctrl+Break to create a dump, and attached to my

open PMR# 54653,442,200.

Now restarting RDi 9.5, since I got a "dump" this time!
<Big Smile>

Hope that helps! If not, let me know what else I can do to help track

this down...

Hi Ken,
Mike is on vacation for a couple of days.
Ctrl-Break should force a dump and the console window should tell you

where it wrote the dump. You can then send this to IBM and we can see what
the program was doing when it hung.

For example when I just tried it, I got:

Send us the .txt file and we can finally see what is going on.

Mike,

Shucks! I forgot to do the Ctrl+Break thing, when RDI 9.5 locked up

again...<frown>

I used RDi 9.5 at home this weekend, no problems, and no Lock-ups....

Now using RDI 9.5 at work, it locks up. I did turn the "Live outline

view"

back on this weekend. Which seems to be the one thing in common, that

"seems" to cause the lock up.<My guess>

I guess this means that I should work from home more.<LOL>

I was debugging this time, and it locked up.

So, when it locks up AGAIN, what should I do to get more information?
Ctrl+Break and then what?

I would say that if you are seeing hangs with debug then I suspect you

may need to stop and restart the debug server on the IBM i. Also, as
mentioned earlier make sure that the jobs that RDI is communicating with on
the i are not waiting on some lock which in turn will make RDI wait.

If your Windows is an "enterprise" config where your user profile

directory (or part of it) is kept on a central server that can lead to
performance issues with Eclipse as some events cause writes to the profile
and if that operation hangs or fails it will hang Eclipse.

Working over a flaky wireless network can lead to issues too I suspect.

Keep in mind too that not ending RDI (or any current Eclipse-based
application) can lead to the workspace being corrupted.

In general I don't find that RDI 9.5 on Windows 7 is any more or less

prone to issues than any other Windows program. Windows 7 seems to go away
at times and leave an app with that white-screen but mostly I think it is
just paging as for whatever reason Windows likes to keep active processes
on disk rather than memory. Now, this could be just in my case as I have
an old laptop with a very slow and encrypted disk.

Edmund,

I make the mistake of turning on the "Update outline view". With that

OFF, it seems to work okay...

:)I created a new workspace, and the new count down begins...

The code I was working on, had NO SQL.<smirk>

And yes, I am using the test patch 2015-10-27.

And my co-worker, whom is using RDI 9.0.1, has been forced to go back to

green screen Debug. She doesn't have the time to load a new version of
RDI...<Sad Face> I told her to create new workspace, and see if that
works. But, she is swamped. So she is using Green Screen Debug. She said
she would try to load RDI 9.5 this weekend...

PS. I have requested a new laptop, hope I get it...<smirk> They still

want to load Windows 7 on it, and not Windows 10.<grin>

Paul,
There is one known issue which causes that symptom and it happens when

doing a Source->Format of SQLRPGLE. Is it possible that you saw this hang
when click on any menu item after doing format of RPGLE with embedded SQL?

If so there is a test fix that will address this if you open a PMR.

Ken,
I believe you already have the test fix. Have you see your "Not

Responding" symptom since applying that test fix?

The only plugin I have is iSphere (latest release). I just had the issue

I've created a new empty workspace now, but haven't used RDi enough since

to see if the problem is gone yet.

I got approximately EIGHT "Not Responding" yesterday, and opened a PMR# #
54653,442,000 - RDI 9.5 has continual Milky-White-Screen-of-Death (Not
Responding)

And while I was talking to IBM support last night. Our other developer

who works remotely, approx. 5-hour drive sent me this plea:

************** SNIPPET ****************
Are you having any issues with RDI when debugging?

Since last Thursday, I keep getting (Not Responding) when I try to

debug....

I have to end it thru task manager.... Then reload... then debug

again...

Sniff sniff......
************** SNIPPET ****************

IBM Support *suggested* that I create a new workspace, and to turn off

Update outline view...

PS. Sadly, there is NO WAY to DUPLICATE this. So I have to manually kill

RDI and JAVAW.EXE in task manager, before restarting...

I was able to duplicate the Error 3-times on my PC, but the IBM Tech did

not get the "Not Responding"...

And of course, I also lose my code changes.

Oh well, new workspace is working for now. This is the 3rd workspace I

have created, since installing RDI 9.5<sigh>

I guess the policy should be to create a new workspace, when you get the

"Not Responding"...<frown>

Check the Progress view to see if there is something running that

prevents you from using RDi at a given moment. I have had numerous
occasions where things stop working because it is running "Initializing
Projects", sometimes for several minutes (and other times it only takes
several seconds). If you don't see anything, try this: In the drop down
on the Progress view, select Preferences, and check the "Show sleeping and
system operations". This might give you some more insight into what is
causing RDi to be non-responsive, for example, a process is running that is
preventing other processes from running. Not a guarantee it will help in
your situation, but as everyone's install of RDi will be different, it
might be the key to understanding what is happening.

Hi,

My colleague and I are getting an unresponsive RDi (9.5) at least twice a

day, and we need to kill it to start again. I've looked in the
workspace .log file, but there are no error messages showing.

It usually happens after selecting an item in a menu, but it doesn't

matter which menu or which item. My most recent event was caused by
right-clicking my connection and clicking the export option, and my
colleagues most recent event happened after clicking the compile menu and
selecting one of the compile options.

I'm guessing it is more an eclipse problem than RDi because the menus are

not always related to RDi functionality. How can I find out what was
causing the unresponsive behaviour? (The error can not be reproduced at

will.)
