JVM Appears to be hung
Hi,
We are in the phase of adapting to the Continuum as CI tool here at our
organization.We are using the latest version available on Continuum Home.
For the testing purposes the Continuum worked beautifully but with actual
project from CVS, its taking quite a bit of time, after the checkout when I
give the build command, after waiting for certain time "JVM appears to be
hung" error comes and the JVM gets restarted, hence I loose the earlier
progress in the build.
Could please someone help out as if it is a configuration problem somewhere
or anything more serious?
The exact error is :
"*
ERROR | wrapper | 2007/11/29 19:17:18 | JVM appears hung: Timed out
waiting for signal from JVM.
ERROR | wrapper | 2007/11/29 19:17:18 | JVM did not exit on request,
terminated
STATUS | wrapper | 2007/11/29 19:17:24 | Launching a JVM...*
"
Regards,
Hemant Malik
We are working with :
1) Maven 2.0.7
2) CVS
3) Continuum 1.1
Need some help
Posted by Tim Schulz <Ti...@bcbsnd.com>.
We are running continuum 1.0.3 on a redhat linux box. We have 28 projects
under the one instance. Everything was working fine until yesterday, then
one of the projects in the "show projects" view was marked with the red x,
but when we go into the build history it shows that it built successfully.
Being relatively new to continuum, can someone explain where to look for the
cause of the discrepancy. Also, can someone point me to some documentation
on house keeping tasks that I need to be doing to keep continuum running
optimally. Thanks.

Hi,
I was able to overcome this problem by deploying continuum war on tomcat.
Just browsing through the continuum bug list i came across some bug that was
related to jvm and jetty, so just as a wild guess i thought of doing it. And
on tomcat continuum is running fine. I know there is nothing to infer from
this fluke but yeah it worked for me.

RE: JVM Appears to be hung
Posted by "Boeckli, Dominique" <do...@eds.com>.
i had same problem and figured out that is was deadlock due to a log4j bug (http://issues.apache.org/bugzilla/show_bug.cgi?id=43568):
This deadlock happens under following cases:
- Proximity RC9 and Continuum-1.1 on same server
- both has a scheduled task at the same time (a purge task for proximity and build task for continuum).
There's no fix for this bug but you can reduce the probability that is happens:
- don't set start time for proximity and continuum task at the same time.

Actually the problem for me is that I don't want the jvm to be killed. After taking sometime the Apache continuum Console restarts the JVM telling " JVM appears to be hung...... " which is killing my enqueued processes and thus losing the schedule :(

Has anyone come across a similar problem? I am not able to cope up with the

Is this a bug or am I lacking somewhere?
