I am experiencing the EXACT same thing, and it's nice to see that someone else has seen it to verify that I'm not losing my mind! It sounds like we have similar environments as well. I'm running version 8.5 Publisher on a 64 bit, 128Gb, 12 CPU dedicated box, so I can tell you with pretty good certainty that upgrading your hardware is not going to solve this. I've looked at other processes running at the same time but haven't found any possible contention issues. And, if I just click the green arrow on Publisher when the error occurs, it magically runs successfully. I have not been able to recreate it on demand, but I do have two jobs that both fail regularly. One of them is a weekly job, and it fails every time it runs via the scheduler. The other is a daily job that fails on Monday mornings. The weekly job runs on Monday morning as well. I have lots of other jobs that perform similar update tasks that run daily and weekly with no issues ever. If I find anything, I'll certainly post it here. I'd appreciate it if you would do the same.
