Hi Evelio, It's very rare to see segfaults from Java in normal circumstances. And it's highly unlikely that the Apache proxy has any effect on it.
There are really only two likely culprits for a segfault in this case: a) A bug in the Java virtual machine - this could be more likely if you are running a JVM other than Oracle / Sun (e.g. OpenJDK, particularly before 7). b) Any native code executed from Java via JNI. Given that you are using Postgres, the only likely route for native code being used with your Tomcat instance is if it is using the Apache Portable Runtime (APR). Whilst this can make the incoming connections more efficient, I've personally had nothing but grief from attempting to use APR with Tomcat.
