We recently upgraded to Casper 9.52 and have been having some issues (Although I am not convinced the update is what caused the issues).
Casper seems to have trouble pushing out software and kicking off processes to the client machines. We have had several packages that go through the motions in self service but never seem to actually do anything.
We checked out logs and we see this group of tomcat errors repeating themselves:

I checked both PKI and Push certificates and neither have expired. Any ideas?
