I've seen more than 10 times on different vps servers that the webmin webserver got killed and so ip:10000 hadn't get loaded !

I want to find the reason, but I coundn't find any log file.

Please guide me !

Are the VPS's you're seeing this issue on OpenVZ VPS's?

How much memory do they have -- you can determine that by running "free -m".

I think it's memory related, but why this just affect on webmin ?

It may be affecting other things too in ways that aren't quite as obvious.

Do you have a /proc/user_beancounters file? If so, can you paste in it's contents?

Yeah, your system is seeing a lot of failures when allocating "privvmpages". You can read about what those are here:

http://wiki.openvz.org/UBC_secondary_parameters#privvmpages

But essentially, you have applications requesting memory that are being denied that memory... and in most cases they'll crash in that circumstance.

It definitely looks like you need more dedicated memory on your server.
