Hello,
I'm seeing these exceptions on one of my 2 nodes. The memory cosumption of this server is now growing for a couple of hours, but I cannot tell if that is related with this. I removed the server from the worker list of mod_jk so it is still in the cluster, but not receiving any requests anymore.
Any ideas about the exceptions. Are they harmless? Can they be related to a constantly growing amount of in-use memory? I'm running Tomcat 5.0.25 on Linux 2.4 and 2.6 with JDK 1.4.2. It runs very well most of the time.
Ronald.
