All of a sudden we noticed emails were no longer coming in and trying to access ISPconfig 3 as usual via https and port 8080 isn't working. Sites hosted are being served though and I can still access the Digital ocean droplet. Anything that I can do to revive via CLI without rebooting? Thanks EDIT: Managed to get access so the problem is the emails no longer being received.
Do you use dovecot or courier as imap and pop3 server? Are you able to send and receive emails with webmail? An easy test if the local mailsystem works is to login to webmail with a account hosted on the server and send a email to the same address that you used to login to webmail. The email shall arrive within a minute back to your account when the local mailsystem works. If the email does not arrive, then check the mail.log
Hi, I'm using Dovecot. I've scrupulously followed the HowTo guide for Debian. Right now amavisd stopped running (according to ps wwwaux | grep amavisd ) In the mail-log I'm seeing this: Code: Oct 14 15:16:03 andromeda postfix/smtp[9007]: warning: numeric domain name in resource data of MX record for pulik.in: 5.133.183.108 Oct 14 15:18:04 andromeda amavis[6354]: (06354-11) (!!)file(1) utility (/usr/bin/file) FAILED: run_command: can't fork: Cannot allocate memory at /usr/sbin/amavisd-new line 3586.

There is not enough free memory on your server. you should try to restart it. If this wont help then you have to assign more memory to your droplet.
The service works once the droplet is restarted. However eventually it fails as described. I'll look into allocating more memory. Silly me thought with nginx I'd be ok for longer. This is memory usage after a restart: Code: total used free shared buffers cached Mem: 1027076 957528 69548 0 6168 112800 -/+ buffers/cache: 838560 188516 Swap: 0 0 0 It seems more memory is 'used' after the restart.. Btw clamav isn't 'working' could it be causing a memory leak over time? I've done the installation at least 5 different times from scratch following the instructions to the letter and clamav never worked.
That's weird I know I had errors at install all the times I did the install and I had a full page of red clamav errors in the log but after restart it's all gone. I'll update here or create a new thread when I get them. So the server has 1GB RAM. It's hosting a few (8) small low traffic sites with some 30 mailboxes spread throughout running on nginx (which you helped me with before) Would you say 1GB isn't enough? Particularly as per memory showed by the 'free' command?
You can start with a new thread mentioning the reference of this tread with link. Yes, Ideally 1Gb is sufficient, please check which processes are eating the RAM Run It will enlist top 10 maximum cpu eating programs.

Just to update. After increasing the RAM I stopped getting the error. Thanks all for the help! So now we're at 2GB droplet.
