    <p>Hi,
<br>
      we are experiencing a critical problem with Bischeck. It's a
      couple of months it sometimes suddenly stops working: the daemon 
      /etc/init.d/bicheckd is running but no check results are sent to
      Nagios. Restarting bischeck daemon fixes the issue.
<br>
      Unfortunately we can't find any clue about the root cause on
      bischeck logs, not even with DEBUG logging level enabled. Redis
      database seems working properly  and no increasing of memory/cpu
      usage are reported on the server hosting bischeck while the issue
      occurs.
<br>
       <br>
      Do you have any suggestion on how to deeply investigate this?</p>
    <p>Regards,<br>
      Francesco<br>
