Hi, can you tell me how to know why webmin and virtualmin stops working? The only solution i have founded is to restart webmin with $sudo /etc/init.d/webmin restart but it dont fixes the problem. Some times i need to try more than once "$sudo /etc/init.d/webmin restart" and it tells me "cannot allocate memory". Sometimes only webmin/virtualmin is down because i can acces my website without problem. I have this problem sometimes after sending mail, doesnt matter if i send 5000 emails or 20,000, it crashes webmin and all stops working and i cant acces even my website. I have a VPS with 1gb Ram and it always indicate that i have 412-560 in use. I will thank any help.
Are you using a OpenVZ based VPS? Those are known to not really play nice with Virtualmin, as they randomly kill processes when resource consumption (not necessarily only memory) reaches its limit.
Details you find in the file
/proc/user_beancountersIm on URPAD.net and i can see that its OpenVZ. Theres is something that i can do to make it work better? Again virtualmin shutdown and cant acces to mywebsite:10000 but the frontend of my website is up and servics working.

Thanks so much.
Howdy,
It looks like you're running into your OpenVZ "numproc" limit. That means your provider has a limit on the number of processes you can run in your VPS, and you've been reaching that limit (11,188 times to be exact).
That's likely the cause of the problems you're seeing.
One option is to reduce the number of processes you're running, by disabling services you don't need.
However, you may also want to talk to your provider about getting a higher numproc limit.

Thanks so much, they modified numproc to 999999. I Hope it works better with that change. Thanks for your advice, otherway i wouldnt know what was happening.
You're welcome. :)
