Hello,
Please give me some guidence.

DB2 V8.2 on Windows 2003 Enterprise edition / 4GB (dual core) RAM.

We have been experiencing some memory shortage. because of this the health monitor is not starting, even db2pd is not working. This is the error in the diag.log.

Even the backup was failed with the follwoing error.

SQL1225N The request failed because an operating system process, thread, or
swap space limit was reached.

I did the db2mtrk on the system and the output is below:

Last month I created new TS with 8K page and created one 8k Bufferpool with 400MB size. But the system is working as normal and there was no memory issues.
But now i am seeing this errors. How can I resolve this? Please post your suggestions.

Thanks.

What else is running on the server?

Currently nothing running on the server and nobody accessing the system.
