Converting process never ending & internal error on dashboard

@jess

I check the contents of this log file:

This is what was found in the log file:

PHP Fatal error:  Uncaught exception 'KalturaException' with message 'Internal database error' in /opt/kaltura/app/batch/client/KalturaC$
Stack trace:

#3 {main}
  thrown in /opt/kaltura/app/batch/client/KalturaClientBase.php on line 894

Are there any other specific logs I should check to investigate this issue?
