I'm looking for more information about the String cache configuration in the Catalina.properties file. I've searched through Tomcat documentation and I can't find any details about this.
We have a servlet that processes requests that can be large, sometimes over 2MB (we have set the MaxPostSize to "0" to handle this). We continually were receiving out of memory messages so we ran Tomcat (5.5) under JProbe and saw that string cache appeared to be the culprit in the heap. When we set the property tomcat.util.buf.StringCache.byte.enabled to false, we were able to successfully run with no out of memory messages and a healthy looking heap. Any pointers to documentation or thoughts about what might be going on is appreciated. thanks Ellen O'S.
