From the source code, this exception will occur slave are disconnected.

But the slaves are online. From the catalina.out, when I check for slave on which these builds were attempted, I don't see any disconnections related errors.

The project uses the "Label Expression" to determine the slaves and we have got some 5 nodes in that label!

What can be the cause of this failures?

Thanks,
Dilip
