I trust the people in the company, but the company's work is with sites that any user all over the internet can access. so we want to perform a damage control if some hacker would gain access to our web server, so if he can - he won't get access to the DB, at least not with our help of displaying t

Memory Leak in Tomcat

Hey, I work in a company which we use Tomcat (5.5.26 and recently we've upgraded it to 6.0.29) to run our application. The tomcat is running on servers with OS windows 2008 R2 STD. The problem is- Until now, we used [b]SQL Authentication[/b] for the tomcat service and configuration (user an

memory leak in tomcat?

Hi, Tomcat 6.0.26 on a solaris. After I unloaded a webapp and asked tomcat to 'find leaks', it reported a webapp leaked memory. However, when I ran a profiler on the heapdump, there are only 2 references to the webappclassloader. Both are weak and are tomcat classes. The reference chain look lik

Hi all, No more help required - I traced back all the references to the Request objects and it did turn out to be a bug in my application code. One of my tracing classes (written a long time ago, before we used Tomcat) was caching all created Thread objects. So when Tomcat decided to allocate ne

try to disable the cache in conf/catalina.properties, at the bottom there is a setting you can set to false tomcat.util.buf.StringCache.byte.enabled=true if the problem still exists, use jmap to dump the heap, and analyse the actual dependencies for mem usage Filip Tom Price wrote: Hi, I h
