I have a SuSe Linux Enterprise Server (SLES10)-based Wordpress server that we downloaded the XAMPP package, installed and have had running successfully for several months. It includes Apache, MySQL, MyPhpAdmin and Wordpress all in one package.
We built a district site with four school sites below it on the same server. Sunday morning (of course) a call came that the district site was down. A restart of the server yielded nothing. A restart of LAMPP yielded nothing. Here is the exact error:
Apache Error: 6054 Invalid Memory Log has taken over homepage for security,
While the LAMPP (./lampp restart) starts/restarts fine, the opening or top page of the site still reports the error. And, there is nothing we can find on the codex.wordpress site or anywhere else on Google.
I found an access_log file that was 1.3 gb in size and zeroed it out with a script and restarted...no luck.
We've had no trouble with this server (no new patches have been added). Wordpress has run flawlessly for months.
Any thoughts...this has become a very visible problem.
