       checking cycle a negative sleep time would have been calculated.

Date: Tue, 13 Feb 2018 18:13:03 +0100 (CET)
package: x2gobroker-ssh
priority: bug


Tried using x2gobroker-ssh ( instead of classical http broker and finaly got it working but in ssh mode, load balancing on my server farm is not working, every session is redirected to the same server (the first one) while it is balanced correctly with the http broker on the same broker server.

I would love to send logs but it seems this broker don't produce log files or I couldn't find a way to get them.
