Re: HTTP Jobs hanging up -- WEB400

OK Questions to help;
1) How many active connections are happening @ once to your HTTP server??  Is 
this HIGH traffic periods that this happens? (Use NETSTAT - Option 3 then hit 
F10 - do you see "Active Connections" and is it REALLY BLOODY HIGH!!  Our magic 
number was in the 500's before the AS/400 didn't like us too much.  If 
threading is utilized (as ALL web pages use this...) your system creates 
another connection per download of say graphics etc... 20 of these kicks the 
system where it hurts the most... 
2) PTF - hope you're being religious about these !! Check to see that memory 
leak PTF's aren't around that may help this.  Due to the nature of the beast, 
SOME TCP/IP PTF's require you to take down TCP/IP which is an IPL if you're 
remote.... 
3) What size AS/400 - how much memory?!?!?  For Semi-Serious Web - 512megs 
minimum.  For Serious web - 1 GIG of memory - for ABSOLUTE Serious web - 2Gig's 
and above... salt to taste... 
4) How many arms for the OS?  Life got NICE @ Home (www.as400nut.com) with the 
fourth arm on V5R1.... Doing this from one disk is suicide... I don't care if 
it's a 120GB Drive... 

Let me know if this helps...

Joel,

Check if the program was compiled with Option(*SrcStmt), to determine if 
you should be looking at the compile line number or the source line 
number. Getting stuck on an ENDSR doesn't seem right.
