Application on JRun

Hi. I posted this under "Other Java Products and Servers" however I did not get any replies. So, trying my luck here. Here goes the issue:-

We have a client application hosted on a JRun server (shared server for multiple applications). We could see java.lang.OutOfMemoryError in the default log which is causing the application outages. Could you please let me know how to get rid of this error?

Also, if someone could let me know if there are any tools readily available to read/understand the trhead dump taken from JRun server.

How to get rid of the error? Either allocate more memory, or figure out why you're using too much.

Moving this post back to the other forum; JRun isn't open source (as far as I know).
