Hello. I did not check the FAQ, but it is down and I don't think my
question's answer is in it.
First my setup:
Ultra Sparc 5 / Solaris 2.6 / Java1.1.8_09 / Apache 1.3.6 / JSDK 2.0 / JServ
1.0
Problem:
Memory usage grows and grows. The system has 256 MB, so it takes it a while
to get to the point where it's swapping at all. When we were running JDK
1.1.7_0x it took 5 days, now it takes 15 or so since we upgraded to
1.1.8_09. Once it gets to the point where it has to bite disk for more
memory, our servlets stop responding. A full stop and restart of Apache
will solve the problem for a few hours, but it does not return all the
improperly allocated memory to the system so it just happens all over again
4 hours later or so.
Potential complications:
1. We are doing a `kill -HUP $mainapachepid` every night to facilitate daily
log rollover. Kill -HUP does not seem to restart the JVM. But then again,
neither does a full kill and restart.
2. We are using a regular ODBC bridge from Intersolv on one of our servlet
zones. We have noticed performance issues and parallel insert problems
using this bridge. Our other zone is using the Merant (Intersolv) JDBC
drivers and is much more stable. Both servlet zones go down when the
symptoms are present.
Any ideas?
