Subject Re: Memory problem with tomcat323 or Solaris
Date Wed, 09 Apr 2003 13:15:03 GMT
If I remember the Oracle docs correctly, there was a note about resource
leaks if you weren't real careful to make certain you close every
connection/statement/result set that you use.

I don't know if that could explain all of the leak, but it is something
to check.
