Guest Geoff Posted April 25, 2011 Share Posted April 25, 2011 What could be happening: 1. We have a process limit that limits the number of processes per user. 2. Your site is running a lot of processes. 3. When you connect to FTP, a new process starts up and you go over your limit 4. Your site returns a 500 because you can't start a new process to serve the request. Do you have a web cron? What scripts are you using? Just what I expected: 1970 boxx 16 0 11512 924 708 S 0.0 0.0 0:00.05 imapd 6701 boxx 15 0 11512 900 704 S 0.0 0.0 0:00.00 imapd 6716 boxx 16 0 11512 900 704 S 0.0 0.0 0:00.00 imapd 14829 boxx 15 0 93984 1020 768 S 0.0 0.0 0:00.44 pure-ftpd Those 'imapd' processes are causing the 500 errors.

Guest Geoff Posted April 25, 2011 Share Posted April 25, 2011 hmm not sure what or why there are 3 imapd processes running? I do have my mailbox on my local system set up to receive mail for my domain. (ie: admin@domain.com) Would that account for those 3 processes running? That's probably it. Every time you connect to our server to check your mail, it starts an imapd process. Those imapd processes are 'squeezing out' your PHP processes that run your site. You might consider using Google apps or something else, as it will prevent this problem from happening. From our end, we have a couple of options: 1. Raise the process limit: higher risk of you increasing the server load & your account being suspended because of that 2. Kill the imapd processes: Would cause errors when connecting to imap, your connections would be dropped while checking mail, your mail client would show errors.

Guest Geoff Posted April 26, 2011 Share Posted April 26, 2011 Right now I'm not seeing any processes on your user account. I don't know why you were getting 'random 500 errors', wait and see if they occur again. Quote Link to comment Share on other sites More sharing options...
jje Posted April 27, 2011 Share Posted April 27, 2011 Looks like there are no 500 Internal Server Errors on http://BigBlackBoxX.com/ anymore. Quote Link to comment Share on other sites More sharing options...
