I have a job that had been working well, and then began to die during validation with "communications link failure" error message. It hangs for a while before it fails. As far as I can tell, the open file limit is fine -- not sure if there's something else that could cause this.

There are potentially a lot of causes for this. See this StackOverflow answer for a summary:
