Unexpected Error While Cleaning arcgisjobs Server Directory

Discussion created by MLF on May 27, 2014
Hello!  We're running ArcGIS Server 10.1 SP1 with two clusters comprised of five machines each.  I suddenly see this error throughout all logs:

      Unexpected error while cleaning arcgisjobs server directory. String index out of range: -1

We are not experiencing any performance issues right now, though our primary web application was intermittently unresponsive until last Thursday, when we restarted AGServer on all machines in one cluster.

I do have access to the directories, but am not 100% sure what to look for. Any thoughts on what this means, what to look for, or how to troubleshoot?  Thanks!
