Howdy!Another issue for you guys :)The system is working great, here are our technical details:CentOS 7.2.1511Webmin 1.791Apache 2.4.6PHP 5.4.16MySQL 5.5.47<1 500 closed tickets3 usersIt's a virtual machine with 2 CPU and 2GB of RAM.The system works fine but after a day, my memory is full. Investigation revealed an abnormal amount of sendmail and postdrop processes.I've narrowed it down to the fetch option of emails through IMAP+SSL in our configuration.We've set the frequency to 1 min.As you can see here:# ps -aux | grep sendmailsupport+ 4921 0.0 0.1 91212 3712 ? S 07 0 /usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t -f supportlinuxsupport+ 5830 0.0 0.1 91212 3716 ? S 07 0 /usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t -f supportlinux... that continues on a long list# ps -aux | grep postdropsupport+ 4923 0.0 0.1 91180 3704 ? S 07 0 /usr/sbin/postdrop -rsupport+ 5831 0.0 0.1 91180 3700 ? S 07 0 /usr/sbin/postdrop -r... that continues on a long listIt's clearly related :)Could you show me the way here? When I killall sendmail and postdrop my RAM comes back available...
