I am using ubuntu 14.04 64 bit. I got the following messege through my email.
/etc/cron.daily/apt:
FATAL -> Failed to fork.
/etc/cron.daily/spamassassin:
channel: could not find working mirror, channel failed
sa-update failed for unknown reasons
And then I cannot login to my virtualmin https://mydomain.com:10000 and got the following message : “Server not found”
But I can login to https://mydomain.com:20000 to check my email.
When I try, login with SSH, everything is okay. Then I reboot and everything is work. I encountered this problem many times and have to reboot to resolve this issue.
I am sure this problem is in my webmin virtualmin but I don’t know how to fix this.
Please help me.

Generally, this message indicates that the apt process is running out of memory. That virtualmin is down as well is a good sign that the whole system is running low. Most likely the database has crashed. You can look for out of memory messages in
/var/log/syslogin order to confirm this.The first thing I would do (if you haven’t done so already) is add a SWAP file to the server. Check out:
I solved this by removing the
apt-xapian-indexpackage. It’s apparently a memory and CPU hog, and it’s run as part of the daily cron. To remove, do the following:sudo apt-get remove apt-xapian-index -yHi! I’ve been receiving these emails on the last few days, after I installed Postfix into my Droplet. Even though I did not see OOM errors in the logs, I created a swap file following the steps from the mentioned tutorial. Let’s see if the problem is gone :)
Thank you!
