Hi again, based on the information that you have multiple processes running, I think that two processes decided to roll files at the same time. This probably has caused a race condition and that again caused the show to stop.
The good news is that this scenario has been adressed in the latest log4net release (1.2.15) and for you this means that you could try to update log4net and see if the issue does no longer occur. Let us know what you try and what the outcome was.
