Plesk 9.5 - can ping but everything stops... Http, mysql, 8443 even ssh...

[psingh]

Hi All,

Anybody's come across this kind of weird problem...
My server (Plesk 9.5) goes totally blackout but you can ping
rest everything is down :
Http - Down
FTP - Down
mySQL - Down
Apache - Down
Cp access : 8443 - Down

SSH - Down

Even ssh goes down... i am unable to trace what is causing it..

Resources : 50 % of ram is free all the time
Storage : 30 % free

I have no clue where to start with.. any body can give me ideas.. what could this be causing..
I have to call or write hosting service provider and ask for a "Power Cycle Boot".. Once the power cycle happens everything is back to normal..

I am clueless at the moment.. any suggestion is appreciated..

Thanks

Most probably there was lack of free diskspace. Check it at least.

Also check to make sure that the services are actually down - if you have console access or the next time it happens ask your service provider to check locally via console. its possible the network card is having issues or something along those lines so that it apepars the entire box went down even though its still running and is just unreachable due to network issues.
