    I got a nasty ConcurrentModificationException while running a job for about 12 hours. The job is performed repeatedly (using the "start" looping functionality). Here's the stack trace: 2012/12/04 06:57:32 - ERROR (version 4.3.0, build 1 from 2012-10-10 10.32.29 by U0165725) : java.util.ConcurrentModificationException 2012/12/04 06:57:32 - ERROR (version 4.3.0, build 1 from 2012-10-10 10.32.29 by U0165725) : at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:953) 2012/12/04 06:57:32 -

I can send over my job but I don't think it would be of any help. Ideas? Thanks

I can send over my job but I don't think it would be of any help. Ideas? Thanks
