[SYS21] SP4 System Manager uplift issues.

We recently uplifted our System Manager to SP4 (leaving our apps at 3.5.0b) on 
our test machine.  We have encountered some problems that I'm wondering if 
anyone else has experienced and can shed light on remedies.

1.     Coincident with the uplift, we noticed that WRKSBMJOB now responds more 
slowly (a lot slower) than it used to.  I've used DSPOBJD *ALL/WRKSBMJOB *CMD 
to see if the uplift somehow created it's own copy of WRKSBMJOB (I realize what 
a ridiculous idea that is...but I leave no stone unturned!) I further looked to 
see if the command processing program QWCCDSUC was duplicated by the uplift.  
In both instances, as I expected, no such duplications were created by the 
uplift.  We have found no other explanation of the slowdown of this command.  
This leaves me with the question...is it really coincidental that the slowdown 
of WRKSBMJOB occurred alongside the uplift or is there something I'm not 
considering.

2.  A few days after the install, the job scheduler began looping and ended up 
submitting 40,000 repetitions of the same job by the time we caught it.  To 
correct this, we ended the job scheduler, cleared the job queue, spent hours 
getting rid of the resulting job logs, and restarted the job scheduler.  Since 
then it has worked fine.  Our GEAC consultant thought this was related to our 
using 99:99:99 as the submit time in some entries.  However, this is the 
documented way to run jobs at day start.

3.  We discovered that Verify Allocations can no longer be run through the job 
scheduler - it must be manually submitted.

In addition to the above, we use Explorer at our remote telecenters and have 
continual problems on individual PCs of Explorer suddenly ending all sessions.  
We are wondering if simply by upgrading System Manager on our production system 
to SP4 these problems will be solved.  Again, does anyone have any experience 
with this Explorer problem and how it was solved?
