Hi,
I have a Sun E4500 running Solaris 2.6. The applications running are Weblogic 6.1 sp2, Oracle 8.1.7, and MQ queue handlers.
The problem that is happening is that after about 12 hours of usage, system seems to run out of swap space.
Killing the weblogic process releases the swap, which would indicate that weblogic is chewing up memory. But pmap output of the weblogic process does not show such a magnitude of increase in its process size.
For example:
Free swap on startup: ~1.7GB
Free swap after 12 hrs: ~200MB
During the same period, the weblogic process size only increases from 280MB to 430MB. Here is the size of the weblogic process, as shown by pmap -x. I am giving the last (totals) line.
On startup: total Kb 389648 188408 13880 174528
After 12 hrs: total Kb 426136 317808 3288 314520
I am giving details below. Please ask me if you need anything else.
Could anyone suggest any ideas? I was thinking, is it possible that freed-up memory is not being reclaimed by the OS, hence swap is getting used up but does not get shown against the process in the pmap output?
