Hi Thanks for your answer. This is exactly how I had it in the beginning. The problem here is that it does not parse all the sub directories. The problem here I think is that as soon as the queue gets empty it hits the undefined entries. But after that, new entries are being pushed into the queue but get ignored because the threads were joined already at that time. Or maybe I misunderstood the logic behind adding undef into the queue. Here an example: 
# ./dpfilesearch.pl --object server:/SHARED --label '/SHARED (test)' -
+-dir /SHARED/tmp/test --recursive  --threads 1
/SHARED/tmp/test/dir7
/SHARED/tmp/test/dir7/dir1
/SHARED/tmp/test/dir7/dir2
/SHARED/tmp/test/dir7/dir3
/SHARED/tmp/test/dir7/dir4
/SHARED/tmp/test/dir7/dir5
/SHARED/tmp/test/dir7/dir6
/SHARED/tmp/test/dir7/dir7
/SHARED/tmp/test/dir7/dir8
/SHARED/tmp/test/dir7/dir9
Still pending in queue: 18

While if I search directly within dir7 I get more subfolders reviled. 
# ./dpfilesearch.pl --object server:/SHARED --label '/SHARED (test)' -
+-dir /SHARED/tmp/test/dir7 --recursive  --threads 1
/SHARED/tmp/test/dir7/dir1
/SHARED/tmp/test/dir7/dir2
/SHARED/tmp/test/dir7/dir3
/SHARED/tmp/test/dir7/dir4
/SHARED/tmp/test/dir7/dir5
/SHARED/tmp/test/dir7/dir6
/SHARED/tmp/test/dir7/dir7
/SHARED/tmp/test/dir7/dir8
/SHARED/tmp/test/dir7/dir9
/SHARED/tmp/test/dir7/dir9/dir1
/SHARED/tmp/test/dir7/dir9/dir2
/SHARED/tmp/test/dir7/dir9/dir3

It is the same if I specify more threads than one. I add a $worker->pending() just after printing the output.
