Running the latest non beta release 3.1.4 on Suse 10 retail. Going through my log files I noticed this error below
ERROR: Parse error at line 70: Option Checks requires numerical argument.
ERROR: Can't parse the config file /opt/zimbra/conf/freshclam.conf

This seems to be tied to how often freshclam will update clamav. Here are lines 67-70 I have never change any flat files in zimbra so this was done on install and seem to be in error. Is there any harm in change the flat file to ensure proper operation of the updates?
