**Steps to replicate the issue** (include links if applicable): * From the bastion, run something like `webservice perl5.40 shell -- perl -lwe '$|=1; for($i=0; $i<3; $i++){ print "out line $i"; sleep 1; }'`or `webservice perl5.40 shell -- perl -lwe '$|=1; for($i=0; $i<3; $i++){ print STDERR "err line $i"; sleep 1; }'` **What happens?**: Output printed often does not include the "out line 0" line. **What should have happened instead?**: All output lines should be printed.
