I have a feeling that, this is relevant entry as, php fatal error has come
only once and imap_debug.log also has only once ERROR recorded.

Please suggest, what can be done to resolve this issue.  This error (PHP
Fatal Error) has come in logs of httpd/error_logs many times on the
previous working day and I had not enabled IMAP debugging.  For this
error, I did not find any trace in horde.log even though the logging is in
DEBUG mode.

Please suggest.
