Thanks for the suggestion Yoav, I do have AccessLogValve enabled but not reverse lookup. I've changed the Tomcat memory settings in registry for the two services so will see if that at helps the memory problem. But I'd still like to figure out why I'm getting such aggressive logging!
As far as the 1.4.1 I'm glad I'm not using it. It's hard to believe that you can't reuse StringBuffers.

It may be that someone just left a System.out.println or a logger statement of a non-debug priority in that part of the code ;) ;) Yoav Shapira Millennium ChemInformatics >-----Original Message----- >From: Januski, Ken [mailto:[EMAIL PROTECTED] >Sent: Tuesday, April 01, 2003 6:22 PM >To: Tomcat Users List >Subject: RE: Out of memory error > >Thanks Nikolaos, > >The multiple (100 per minute) mapping server lines occur before the out of >memory error.
