Hi, I'm not know what happened but since 2 days I see alerts "httpd is down! Rescue will not help!" and rescue module restart Apache every minute. , but Apache is running properly... I was disabled HTTPD monitoring, but alert is still displayed. I was restart Apache by /etc/init.d/apache2 restart, and this is not help. System is Debian 6, 64bit, Ispconfig 3.0.4.6 Thanks for your help...
The alerts are from ispconfig rescue system. Check that apache is listening and rechable on localhost.
Problem solved - apache produced mass error logs for one of site. Apache was work, but maybe to long respond, and that was the reason for restarting Thanks!
Sorry for to re-open this. I'm having same problem. ispconfig syslogs writing tons of messages httpd down!! Rescue will not help. Where do I check this and what should I observe exactly ? Ubuntu 16.04., apache 2.4. Webserver is showing offline.
Yes ok, but what should I check ? What should I change and where ? The messages I already disabled, but seems that some heavy weighted customer software is crashing constantly the server. Customer upgraded his Prestashop and also his WP and now the disk consumation rised up from under 50% to about 95%. Unfortunately I haven't set quotas before. Now it's done and this customer I moved to another VPS with bigger space. As for first thing I also uninstalled fail2ban for to get more space, than I moved the sites. Now I'm installing fail2ban again and we will see... I had also to kill some broken semaphores processes.
