Hi,

Decided to try ALPHA4 and Samba 4.3 and 4.4 doesn't seem very happy.

Fatal error 'mutex 0x8013ec000 own 0x18cdc is on list 0x8112161a0 0x0' at line 153 in file /usr/src/lib/libthr/thread/thr_mutex.c (errno = 4)

This occurs immediately when you start Samba so it's easy to replicate.
I know that 4.3 worked on r298887 for sure, I'm going to try this in VM too but I'd apperciate if anyone else could give this a go.

I noticed that there were some changes in libthr which might be a clue....

Best regards,
