Work Dir is not cleaned up

[Thorsten Büker]

Dear all,

since migrating our mailing systems, which consist of MailScanner 
between two instances of postfix, into virtual machines by using the 
http://linux-vserver.org patch, the working dir is not cleaned up anymore.

The temporary directories, each named with the pid of previously stopped 
childs, are neither deleted after starting new childs automatically nor 
after stopping the whole MailScanner.

Google did not lead to any hint, yet, but the changelog states, that 
version 4.50.15-1 "fixed bug where temporary files were not cleaned up 
properly". Alas instead of compiling a newer version I'd prefer to keep 
the original package (4.41.3-2) shipped with Debian Sarge on the 
productive machines.

So, do you have any hint for to look for the reason or is there any 
reason not to stop MailScanner by a nightly cronjob, delete the working 
dir, and start it again?

thanks in advance,
   Thorsten
