Can you post the exact messages that appear in the log

Also, are you current on the latest v5r3 CUM, HiPer and Java Group PTF's ?

I will try and do my best to explain the problem but it has been going on
for about 6 months now so I might leave something out.

Here are details of the system
iSeries 270 with 3gb ram, 1 partition, ~180gb of storage
We are currently running a Homegrown accounting system (all green screen),
Domino and websphere.  We don't use websphere currently but it is running.

We started getting "Insufficient memory" on the clients back in April.  We
tried just restarting notes and that didn't help, I think we had to IPL to
get domino to work again.  We have since fund out how to clear the shared
memory through iSeries navigator, so we don't have to IPL it just shutdown
Domino, cleared the shared memory, start Domino. We would be good for
about 3-4 weeks before it would happen again.  At the time we were running
Domino 6.5.   Our business parter suggested we upgrade to 6.5.4 and
upgrade the ram (we had 2gb, now 3gb.)  we have since done that and the
errors and domino lock ups come more and more often now.

We have been dealing with IBM but they have not really been any help.  We
have been sending them memory dumps and other debug info but have not
gotten a satisfactory answer from them.

We found the ConstrainedShMEM setting on notes.net and set it to 2gb.
Since then we still get the error messages but the server is not totally
locked up like it did before. We can actually get into Domino and do some
poking around before we restart it.

Our NSFBufferSize was set to 300mb and the
Database.Database.BufferPool.Peak.Megabytes = was always at 300mb.  We
have since changed it to 500mb and it is usually at 498 now. Should we
increase this more?

For the last month it has been crashing every Tuesday morning.  The 400
IPL's on Monday morning and Domino shuts down everynight from 1am to 4am
for backups. So it IPL's on Monday morning, runs fine all day monday.
Shuts down Tuesday morning, backs up Domino, restarts at 4am.  By ~5:30am
on tuesday we start receiving the "insufficient memory errors" in the log
file, but it doesn't yet effect the end user.  By about 7:30 or so end
users start getting the message on their desktops.  So we shut down the
server, clear the shared memory and it usually runs fine until the next
Tuesday.

Any Ideas?

Last Tuesday afternoon we upgrade to 6.5.4FP2.  It ran fine Tuesday
afternoon and all day Wednesday, then on Thursday morning we started
getting the same problem again!

Last week we shutdown Websphere and Apache since we don't currently use
either (leftover projects from an old employee.) So far this morning, we
have not gotten any insufficient error messages.

We had Websphere and Apache running before with 6 and with 6.5 and no
problems that I can recall.
