Hi,
We are using tomcat 6.0.26 on windows 2008 web server, with Jdk 1.6.32
installed on the server.
The
server seems to be running smoothly most of the time, but suddenly the
memory used goes very high and tomcat stops responding, the logs don't
show any out of memory or thread exceptions.
There is a similar thread published a week ago.
It can be caused by almost anything, and my last suspect would be Tomcat
it self.
Most of time, the cause is some programming error, like:
- missing step out of recursive loop
- loading too many objects is memory (for example, when using JPA where
of these sound like reason. It would be great to get pointed in the
right direction.
Regards,Ayush

new to this I am not sure what might be causing this, is it log4j
or something else like dbcp pool.
Help appreciated.

help to identify the cause.
Seems too little information to deal with such big problem.

In particular, note removeAbandoned and logAbandoned. These will impact

on reqular
intervals, Log4j is used in those methods, so will cross check those methods
again.
Really appreciate your time and help.

Thanks Everyone for the help, I will enable thread dump for my
Tomcat, just reading up on how to get that done. My database
connection string is given below.
You don't need to enable a thread dump
as
expected as tomcat still hangs once in 12 hrs, but I know where to look.
