Description Grace Chen (mail address dead) 2013-01-23 18:51:39 UTC 
We use dfree.sh script in smb.conf.

 dfree command = /opt/VRTSnasgw/scripts/dfree.sh "%D" "%U"

When this script in invoked by smbd, we see many error messages shown up in /var/log/messages as following:

2012 Dec  7 10:42:50 sfss90_02 smbd[11025]: [2012/12/07 10:42:50.421541,  0] smbd/dfree.c:126(sys_disk_free)
2012 Dec  7 10:42:50 sfss90_02 smbd[11025]:   disk_free: sys_popen() failed for command /opt/VRTSnasgw/scripts/dfree.sh \"SFS-TEST1\" \"host236u10\" .. Error was : No child processes

It seems that sys_popen() fails to handle some signals. Could you please help investigate?

We found the issue on 3.5.16, however, further testing showed that same issue exists in 3.5.19, and 3.6.8 as well.

Thanks.

git-am fix for 4.0.x and 2.6.x

Already went into master, just need a +1 for 4.0.x and 3.6.next (patch applies cleanly to both branches).
