Hi guys, I've got an ISPConfig 'the perfect server' on Ubuntu 14.04, and I spent the weekend setting up Monin and Munit for it according to the tutorial on this site. Everything was fine for a couple of days, but recently (yesterday & today) I can no longer access any of my sites - every port comes up connection refused (ssh, ftp, smtp and http). Yesterday I was able to fix the problem with a restart. Today, that doesn't work. dmesg reports a segmentation fault in php-cgi, and I know clam and amavis are struggling with the amount of RAM (2GB) and crashing at times. I've been looking into ways of reducing memory usage, we've only got a half-dozen sites so shouldn't need much more resource. Not sure if this is relevant. Any assistance appreciated. I rely on this server for my business. So far no work today - and this isn't good. Thanks in advance.
