One of the hardest things about debugging issues like this is that it is unpredictable which clue will give us enough information to make progress. In this case it was Sander Plas who was able to get the gdb backtraces of the stuck processes, and those have essentially isolated the problem. (Our inclination is that this is a tdb mutex deadlock). Furthermore, it seems likely that this happens most often in production, rather than in test, as the timing of connection shutdowns would appear critical, so it didn't show up in 'make test'. (We also don't currently have a check for stuck processes in the test cleanup as we probably should) As I said, I'm sorry for your frustration, and hope we will have a fix to this shortly.

thanks for your attention.
temporarily with the following script I'm looking at myself.
#!/bin/bash INTERVAL=180 LOG=true function log { if $LOG; then echo $1 fi }
while true; do testx=`ps -auxw | grep "smbd" | wc -l` testy=`netstat
-ap |
grep samba | grep sock | wc -l` if test "$testx" -gt "50" -a
"$testy" -gt
"50" ;then echo "samba problem" service samba restart else
echo "samba no
problem" fi sleep $INTERVAL done
