3.3m4 often hangs (cpu 100%)

henk de boer Master

Hi,

 

Having used m3 since it came out I never experienced a hang. However, since I upgraded to m4 I frequently experience hangs when validation is taking place, typically right after I pull & update a major amount of changes from a repository.

 

When the hang happens, the CPU is at 104%. One page specifically always causes the hang (also on the systems of my co-workers who run m4), I removed it from the project and then validation succeeds but after the mentioned pull & update it often hangs again without a clear indication of what it is hanging on.

 

I wonder if anyone else is also experiencing such hangs.

    Could you attache the stack trace?

    You can get in in console via the following commands:

    1. jps

    You probably will see two java processes. One is your Eclipse and the other one is jps.

    2. jstack <eclipse_process_id>

    In my case there are typically quite a few more than that, but I know which one I need

     

    To isolate the problem, I installed Eclipse 3.7.1 completely from scratch. Changed nothing and installed only Jboss tools 3.3m4, created a server for JBoss AS 6.10, created a dynamic web project with JBoss 6.x as target runtime. Added only the problematic file.

     

    Got the hang nearly immediately. This time I tried OS X where the CPU is at a near constant 108.9% now, but I also tested this on Linux (Ubuntu 10.10 and 11.10), Max OS X 10.6 and Windows 7.
