From time to time httpd.exe process uses nearly 650 MBs of memory according to task manager on a Windows NT machine with a physical memory of 750 MBs, and the server becomes unresponsive till a restart.
We are using iPlanet version 4.1. Shall we suspect memory leaks?
Have you got your iPlanet 4.1 problem answered or fixed? I have similar issue with iPlanet 4.1 SP6 on Solaris. With 115 concurrent users logging in, http daemon becomes unresponsive. errors log shows exiting from JVM. Out of memory and so on. My application catches memory exception when JVM can't allocate memory. Since these exceptions are catched, so app server never crash nor hang on these exceptions. iPlanet 4.1 SP 6 lists/fixes Java memory Leak problem. I can't find anything on describing the problem so don't know if the patch helps me.
