Memory Leak Problem?
Hi,
I'm involved in a project using Tomcat 3.2.2 on Solaris 2.6 with JDK
1.3.0_02.
We have a web-app that has a lot of intensive File I/O. And it uses
sessions.
When we logged in and did some intensive I/O process, switching between
the different apps quickly, it was observed that the memory usage
gradually increased. After waiting for some time, the memory usage did
not come down.
Is there any memory leak problem with Tomcat's 3.2.2 session management?
Would a memory leak occur if your tomcat server cannot write to the web
client's TCP socket? (Which does occur when switching between these
applications from the web client.)
Cheers,
John Clark

Did you close you I/O objects? That can cause more memory usage.
