This is actually a kernel bug with fcntl(F_SETSIG) no longer working. I'll file a kernel bug shortly. |
Description of problem: On FC4 server with samba-3.0.23a-1.fc4.1 and kernel 2.6.17-1.2142_FC4, we are seeing smbd crash periodically with SIGIO. This causes the windows client to report "Delayed Write Failed". It appears that it recovers and reconnects afterwards, but apparently data could be lost. Example strace: 21136 13:06:09 getegid32() = 0 21136 13:06:09 setgroups32(3, [1001, 1002, 1020]) = 0 21136 13:06:09 setresgid32(-1, 1001, -1) = 0 21136 13:06:09 getegid32() = 1001 21136 13:06:09 setresuid32(1017, 1017, -1) = 0 21136 13:06:09 geteuid32() = 1017 21136 13:06:09 fcntl64(11, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=7124, len=1}, 0xbfb424a4) = 0 21136 13:06:09 --- SIGIO (I/O possible) @ 0 (0) --- 21136 13:06:09 +++ killed by SIGIO +++ A mention on the mailing list extists as well: http://lists.samba.org/archive/samba-technical/2006-February/045477.html Version-Release number of selected component (if applicable): How reproducible: Very.
