Hey all,
We're running AR System 7.5 patch 004 and we are finding that our server is
eating up memory and not releasing it. We are in the UAT process and have
roughly 10 testers testing the system. During this time we've noticed a
huge memory allocation and eventually the arserverd process would consume
2-3 gigs of memory and all the swap space, at which point the machine comes
to it's knees and the process needs to be forcibly killed or the box hard
restarted.
I remember reading somewhere that the AR System doesn't release memory for
large queries, but instead just reuses the memory address space. Is this
still true for 7.5? Are there any type of performance configurations I can
add to the ar.conf file to allow the AR System to release the memory it
allocates? Or to prevent a query from taking all the available memory on
the box?
I thought the AR System used temporary file storage for storaging a large
SQL result? Our 6.3 AR System stores temporary query result files in
/var/tmp/ARpen* files, does 7.5 not do the same thing?
I just thought I would ping the list before I open a ticket with BMC and see
if anyone else is seeing a memory leak or has had this problem occur to them
in the past. Though I'm not sure who all is running the latest 7.5 AR
System.
Any help would be appreciated as I'm not sure what BMC will want me to look
for to determine a memory leak and I don't like to engage them without some
sort of proof that one exists.
Our server specs are the following:
System Configuration: Sun Microsystems sun4u Sun Fire V210
System clock frequency: 167 MHZ
Memory size: 4GB
==================================== CPUs

AR System 7.5 patch 004
Apache Tomcat 5.5.28 / Midtier 7.5 patch 004
If you guys need more server specs let me know. We are trying to replicate
the issue but we are unsure how it happens and don't really know where to
start.
Thanks for the help.
