Syslog Messages from Remote Server are not writing to Log File Anymore

Hello All,

Server: SUSE Linux Enterprise Server 11.3 (x86_64)

Syslog-ng Version: syslog-ng 2.0.9

We have configured a Cisco router to send it's log messages to this server listed above. This has been working just perfectly
for the last couple months, but we had never setup the log rotation part of it and the log file was getting extremely large.
So I decided to manually move the current log file to a new file and then ran touch on the original log filename to re-create it.

Code:
/var/log# mv remote.syslog.log remote.syslog.log_20140925
/var/log# touch remote.syslog.log
/var/log# chmod 640 remote.syslog.log
/var/log# bzip2 -z remote.syslog.log_20140925

I did this so I could compress the original log file with bzip2 seeing how large it was getting... Now, the log messages
from the router are not being written to the log file anymore. I ran Wireshark and I could see the router sending the messages,
to the server, yet nothing is being written to the log file anymore...

Did I mess this up somehow by moving and re-creating the original log file?

If anyone knows how I can fix this please feel free... But any thoughts or suggestions would be greatly appreciated!

Thanks in Advance,
Matt

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME
doveadm-log - Locate, test or reopen Dovecot's log files SYNOPSIS
doveadm [-Dv] log errors [-s min_timestamp] doveadm [-Dv] log find [directory] doveadm [-Dv] log reopen doveadm [-Dv] log test DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of the *log_path settings. OPTIONS
Global doveadm(1) options: -D Enables verbosity and debug messages. -v Enables verbosity, including progress counter. COMMANDS
log errors doveadm log errors [-s min_timestamp] The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred since the last start. -s min_timestamp An integer value, representing seconds since the epoch - also known as Unix timestamp. When a min_timestamp was given, doveadm(1) will only show errors occurred since that point in time. log find doveadm log find [directory] The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log files. log reopen doveadm log reopen This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings are configured in /etc/dovecot/conf.d/10-logging.conf. This is for example useful after manually rotating the log files. log test doveadm log test This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior- ities are: debug, info, warning, error and fatal. EXAMPLE
This example shows how to locate the log files used by dovecot(1). doveadm log find Looking for log files from /var/log Debug: /var/log/dovecot.debug Info: /var/log/mail.log Warning: /var/log/mail.log Error: /var/log/mail.log Fatal: /var/log/mail.log REPORTING BUGS
Report bugs, including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>. Information about reporting bugs is avail- able at: http://dovecot.org/bugreport.html SEE ALSO
