I tried it again this morning and was able to change the password with only one segmentation fault error. All is good since then. Must have been just left over Apache sessions in play.

I checked using "find" and there is no evidence of a rootkit or changed files in /usr/bin or anywhere else for that matter. Why would the system do segmentation fault errors for only one site on the server?

On one particular site that runs Joomla and vBulletin, when I went to change the MySQL user password (they share the same user over several databases), Apache started spewing segmentation fault errors: [Mon Nov 23 02:46:51 2009] [notice] child pid 16419 exit signal Segmentation fault (11) The minute I changed the password back, they quit. Even restarting Apache wouldn't fix the problem. Have you ever seen this before and what is causing this? The only time I saw Segmentation fault was after a rootkit attack. Disastrous! ls -l /usr/bin Look for funny ownerships - other than root - this could be nasty.16167_2.html (attatchment)(tag is disabled)
