What's with that server AGAIN?

[Nova]

I know PM, it was unreachable since 7 last evening. I have been on their backs since then. No answer to anything but ICMP. But PM, its not the router. They did nothing but press the reset button now ...

Thats the last message in any log before the server crashed. PM, memed, is that of any use to you ?

hmm looks like the VM tried to access the swapfile beyond it's acctual size.
i will check swap settings ASAP.
also i noticed the server beeing dead since 19:42 yesterday evening (planned to fragg on the server at 20:00) and i checked the CS server randomly until 22:00, also IRC was dead at 19:45.

Cheers memed

Everything has been dead since 19:42 yesterday evening ... and i start to think its actually NOT the hosters fault (for once at least)

yes, sorry, we've been crossposting. I've edited my last post. I agree with memed, this is a nasty problem. Either the HDD is starting to die, or something else, but I'm not sure what would cause the swap space to be reported incorrectly...

when it's full, it will get a access denied, though im not shure it will yield that error...

what was the reason for the long downtime yesterday ? a problem with the server or a problem with the hosting company again ?

[Onno Kreuzinger]

it was the server spiraling down for no obvious reason, and the hoster for not reacting from friday night until this noon.
i wrote 5 emails (saturday early moning {but not very specific}, saturday noon, sunday noon, one early this morning and one this noon). 3 times they send an acknowlegment, one time they realy did restet the server...
for the server it is not an option to stay on that hardware/software for much longer. there has allready been one (shorter) outage last week and Nova is in search of a new hoster (problem: setup fee's).
I will _try_ to track the real cause, something can't malloc memory, there is one GB of RAM and supposed Stefan fixed the memory leak in relabot there should be no software eating it up, but i'm no exert for irc servers, so if anyone knows of dos attacks against the IRC or other servers we use, please tell me (or all of us) your suspicions, it is better to hunt shadows that waiting for the next dead time.

there are no malloc problems that i am aware off. I do have fixed a few memory 'access' problems. Afaik the new rb (which does not want to compile, check the other forums) is 100% memory leakage free
