>Why do you think the machine is running out of memory?
I'm starting to blame it on our ODBC drivers - Merant/Intersolv SequeLink
4.5.1 for Solaris client and a SLSQLServer on NT.
>Can you see the problem growing slowly
yes. Over the 15 day period before everything goes to hell top reports that
the system has less and less memory.
>Also, running "pmap -x" (in /usr/proc/bin) on a representative sample of
programs
Thanks for the pointer - pmap is a cool tool I didn't know I had. Time to
RTFM on that.
>If stopping and starting Apache doesn't fix it (and you have said it
doesn't), then you really have to carefully consider what else is running
on the system.
Nothing else - just ApacheJserv. It's getting a decent amount of traffic,
and it's somewhat i/o intensive with search and replaces and database
inserts and the like. It's doing some 3000 db inserts a day or so, but the
http traffic is rather low.
>How do you "fix" the problem? Do you have to reboot?
Yes. We noticed after big benchmarks (10 concurrent (1000 (jserv/db insert
request))) that the system would sometimes become unstable, so we went to a
db queue structure with serial inserts. We also have the box patched to
current levels. That seemed to add stability, but we still have this
nagging 15 day problem. A reboot is usually necessary, this is the thing I
am really trying to avoid.
