Hi Everyone,
I seem to have an issue with an exec task not closing the ssh connection
it opens. Basically we use CruiseControl and Ant to build and deploy
our code. In the CruiseControl build.xml I have an ant task that ssh's
to a remote server and starts a shell script. Once the script completes
CruiseControl continues along its merry way...until recently. Now at
seemingly random times, one of these ssh connections will not close thus
causing CruiseControl to hang. If I kill the process, CruiseControl
continues like normal.
I am using CruiseControl and never saw CruiseControl hanging because a
build is hanging. However if CruiseControl is configured with only
one thread, only one build can run at one time.
The ant task is:
<exec executable="ssh" logError="true">
<arg line="${remote.host} ${sudo.cmd} -u
${username} /usr/local/qa/deploy_build.sh ${deploy.param}" />
</exec>
You could use the <sshexec/> ant task instead which is shipping with
ant, and requires jsch.
Maybe the underlying problem is that sudo is now configured to request a
password ? or your remote user is expired ?
You should try to run this ssh command by hand to see what is wrong.
This had been working fine for the past year. Now we are having issues.
It started when we migrated to a new build server. It has a more recent
OS (solaris 2.10 instead of 2.9).
I tried adding the timeout attribute to the exec task, but all that
seemed to do was hide the stuck process.
Any thoughts or suggestions are much appreciated!
Thanks,
Barry

Antoine
