Problem with Vserver and system not reachable

[pontifex]

Hi ISPConfig Forum,

i have the following Problem. I registered a vserver and installed ispconfig on it. normally on a hardware serer, (non vserver) ispconfig works fine. on the vserver after some hours the server is not reachable anymore. the ispconfigpanel under 8080 and the smtp port can not be accessed. after a reboot of the vserver the systems works for a while.

are there any changes to be made because of the vserver?

Cheers

Hi,

What are the specifications of the VPS (vserver)? How many sites,email,mysql do you host on the vserver?

Do you monitor your server to se bottlenecks at the time server goes down? What about log files and load values ?

Hi,

there is one domain on it.
no mysql (except ispconfig db)

no ftp, http

no traffic load. the vserver should (if the system is stable) act as a mx loop. no other services will bei running on the vserver except smtp.

If the server become unreachable, check the server limits with:

cat /proc/user_beancounters

Hi Till,
i tried to reach the server. Due to that purpose the server failed. after a reboot the command "cat /proc/user_beancounters" gave the following output:

What can i do?

PS it is a server from server4you . de

The limits for numfile and numothersock are too small. You will have to ask them to set them to a higher value.

[pontifex]

Hi Till,

thanks very much for the REALLY fast replay. What do you suggest should the values for

numfile and numothersock

be?

Cheers

[falko]

I'd double both values for the beginning.
