system crash / need help!
Hi,I got weird problem with my dedicated (posted in the dedicated forum, but got no response - probably wrong forum?

Today, I was unable to connect to http, ssh, ftp, pop... in other words i was unable to connect to anything.
On the other hand, I was able to ping it. Though, pings were very bad (the were average 160ms, with around 36ms normally).
My monitor software (monit`s last version) didnt send me any alerts. Looks like the system crashed, but why I was able to ping it then??!
The logs is empty. No errors at all.
What that could be? Where I can check that? What should I do?
Did anybody got the same problem? Is that hardware problem?
My system is: dual p3, 1 gb ddr ram, ide 8mb cache drive. I have not heavy usage for such configuration: ~40k hosts/day.
Please help!
Thanks.
