crash, struts - pageContext?

[Tomas Zverina <to...@templation.net>]

Hello,

I would like to ask you about your opinion or experiece with the
following problem.

Our application is an EJB application, running on jBoss (3.0.2 or
3.0.4), J2SE 1.4.1 and Struts 1.1.b2.

The primary problem is an OutOfMemoryException which occures on WinNT,
where the application is deployed. After repeating HTTP requests
java.exe allocates about 100MB of RAM (suddenly) and keeps alocating.
During 2 minutes it allocates all the free memory (1.5GB) and ends with
OutOfMemoryException. During this crash, browser gets its response and
the crash continues without user interaction.

Crash cannot be repeated by requesting the same actions, we can work
with the application as normaly and the crash will not occure. It
doesn't depend on data or operations order. It occures on random basis.

On linux, and this is the secondary problem, I was not able to repeat
this crash. Instead of this I get following error:

Unexpected Signal : 11 occurred at PC=0x4054E6DC
Function=array_addressing__5Parse9BasicTypeiPPC4Type+0x118
Library=/usr/java/j2sdk1.4.1_01/jre/lib/i386/server/libjvm.so

JSP page I'am requesting can be pure JSP without connection to SQL etc.,
a few struts tags are enough to crash. Specially "iterate" and "define",
I suppose that an implementation of pageContext is responsible for this
bug - not Struts themself.

I have tried another versions and another hardware with the same
problem. Used computers can be only classified by "an average number" of
responsed request until crash.

I'am not sure if those problems (Win X Linux) bear of each other, but
they are caused by the same actions.

Have you got any ideas or experience with this behavior?
Or any hints how I can recognize what exactly goes wrong?

Tomas Zverina
