Yes is does seem like a race condition. It only happens consistently on my 
main FE/BE (E6300, 2GB RAM). On one remote FE (E6320, 2GB RAM) it happens 
occasionally. On my other frontend (EPIA 1Ghz, 512MB RAM) I think it's only 
happened once.

All recordings are stored on my backend and the remote FEs use myth streaming.
