I am experiencing this issue constantly with my Fedora Core 4 installation. I have tried to install/ reinstall this computer many times from scratch but this error is not getting resolved and I cannot get to the root.
/etc/cron.daily/0logwatch:
Use of uninitialized value in numeric le (<=) at /etc/cron.daily/0logwatch line 683.
I am usually okay for one week and then cron starts generating this error on daily basis. I past I was running yum nightly updates but this time I updated my system once manually and not enabled automatic updates.
In my previous installation I was also experiencing some issues with ISPConfig application I was using and the feedback I recevied was that it is some sort of segmentation failure which are usually caused by memory or disk errors.
I have ran memtest86 and microsoft's memory test applications thoroughly and did not find any problems with memory. I have successfully formatted hard disks with DOS and linux installation without any errors, also changed partition sizes but nothing has made any difference.
This time I kept log of all emails from system and logs and cannot find any obvious change on the system at all which could have caused this error.
I have tried few hosting control panels but ISPConfig is perfect for my needs, other are too complicated and compliant with other distributions like Debian but I like Fedora more and would like to keep myself on the same.
Can someone please put me in right direction how to figure out what is going on?
