pending - Waiting for next available executor on master

AnthonyJ-2
My customer has several jobs which are tied to the 'master' which is
setup for 25 executors. We occasionally see these jobs hung in the
Build Queue with the message "pending - Waiting for next available
executor on master".
No other jobs are in progress on any of the executors when we see this
message. All executors/slaves are idle. The configuration of the job
hung in the queue uses a lock, a remote trigger, a '0' for quite
period and a '2' for SCM retry count. There are no relevant errors in
the system log. Nothing at https://wiki.jenkins-ci.org/display/JENKINS/Executor+Starvation
seems relevant.

Does anyone else have an idea what could be going on?

Thanks
Anthony

Another thing to note is that eventually this issue clears itself up
after several minutes have passed.

Just a guess: if I remember right the Mercurial and Git plugin both
use an executor on the master for polling. Set the number of executors
to 0 on the master to check wether this might be the problem.

Thanks for the idea Mirko. This Jenkins uses the SVN. I checked the
"Max # of concurrent polling" on the system configure page and this
field is empty (no bounds).
I checked the load on the Jenkins server when the pending master
executor issue arises and it is almost idle.
