Logfile not accessible

Greetings everybody,

I have this one log file that is going from yellow to green back to yellow every 3 minutes. The xymon-client is installed on a MySQL server.

When the BB Display goes to yellow it indicates:

Warnings in /opt/mysql/log-error/zzzzzz-error.log yellow Logfile not accessible

But I see activity in the log.

However, the log file does exists there with the proper permissions for everyone to read. -rw-r--r-- 1 mysql mysql 44143540 Oct 29 10:02 zzzzzz-error.log

When it turns green, it indicates: No entries in /opt/mysql/log-error/zzzzzz-error.log Full log /opt/mysql/log-error/zzzzzz-error.log

But I see activity in the log.

What could be causing this flopping from green to yellow and back to green? Thanks in advance.
