Description theshadow27 2009-02-27 18:52:22 UTC

Race condition (100% x2 CPU usage) when deploying web application 

Trying to deploy web application (via right click on project -> deploy) the logs (from inside of netbeans, and
catalina.out) show tomcat started:

INFO: Server startup in 15270 ms

However the IDE indicated "Waiting for tomcat..." and did not deploy. CPU went to 100% and stayed there. I tried to get
a CPU profile, but the entire UI stopped responding. I manually closed Tomcat (kill + PID via terminal) instead of NB to
at least get the exception report in. The cpu usage dropped, profile screen loaded. All operation back to normal. 

Three possible causes, but I don't have enough info to make the call:
1) OS X <-> Tomcat binary communication  
2) Webapp deployment code
3) Tomcat exception handling

Tomcat is version 6.0.18. NB build 200902231810, downloaded in the 6.7 M2 distro.

Generating a new profiler snapshot should be carried out under the status lock thus preventing the possibility of inconsistency between the instrumented method count stored in the snapshot and method ids contained there.
