Hi all,
I use this command on my servers to test locally that Samba is alive and
well:
smbcontrol smbd ping
However, it suddenly stop working on one of the several identical servers,
and I cannot figure out why. ping command says "no replies received",
while
log.smbd says that it received a ping message, but cannot reply because
permission is denied. Which permission?
$ sudo /usr/bin/smbcontrol -d 3 smbd ping
<...>
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Registered MSG_REQ_POOL_USAGE
Registered MSG_REQ_DMALLOC_MARK and LOG_CHANGED
fcntl_lock: fcntl lock gave errno 11 (Resource temporarily unavailable)
fcntl_lock: lock failed at offset 0 count 1 op 6 type 0 (Resource
temporarily unavailable)
No replies received
log.smbd:
<...>

System is Ubuntu 14.04 x64, Samba 4.1.22.
This is all done by root, apparmor is enabled but doesn't indicate any
denied operations.
