Problem with heaps of sleeping smb processes due to panic action

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi! 

We're running Samba4 (Version 4.0.0beta4) and are experiencing problems with smb_panic actions which result in loads of sleep processes in the end taking down the entire machine. This problem did not exist in prior builds for us (upgraded from alpha17 to beta3 and then beta4). Are there any specific log extracts I can supply that can help someone pinpoint the problem? log.smbd seems to indicate the following:

but I'm honestly not good enough to dissect the problem.
