[Users] Failure to connect to engine with Nagios

Hello, We are having some trouble with the Nagios plugin for oVirt. From time to time it stops working and it isn't able to connect to the engine. The error that we get apparently indicates a failure to read the file where the session cookie is stored: RHEV CRITICAL: Can't connect to RHEVM-API. Unsuccessful stat on filename containing newline at /usr/lib/nagios/plugins/check_rhev3 line 1411. Any suggestion on how to diagnose/solve this issue?
