Tomcat – Slow tomcat startup

I have very slow Tomcat start with app deployment.

Environment:

OS: Scientific Linux 6.3 x86_64

Java: 1.7.0_9 64bit

Tomcat: 7.0.32

startup tooks 150s and java process is at 100% CPU

I tried same webapp on another server (with same HW parameters) but on OS 32bit with java6 32bit and tomcat 7.0.19 and on this server tomcat starts in 30s.

I tried same java and same tomcat on new server without much success.

here is parts of tomcat logs when it waits for something…
