crash linux

[feanor]

hi , i am using ubuntu 14.04

my server goes offline in evenings every 2 days , today it happened 3 times and it made me crazy really. it was happening 1 month ago , idk how it fixed but didnt happened for 1 month. now again started. there is no reports on all logs (kern,system etc) i also tested my ram(i thought maybe a hardware problem) but still i couldnt find my problem. can anybody help me about that ? thx a lot

You may ask your hosting company about that. Maybe they had some problems.

[kung foo man]

checked game logs aswell, or just system logs? using libcod? might be just somebody causing the crash.

and check the server console output itself, e.g. keep the screen session running when server dies

[feanor]

there is no log about problem really :/ i checked also cron jobs but nothing to find. i googled if some users have same problem , i found people with same problem but there is no solution :/

just wondered if it's a power supply problem , can a linux server logs power supply ?

[feanor]

and its always happening in the evening also weird :S

Post "free -m" command run in the evening.

Also post "uname -a" at any time of day.

when i free memory server crashed :D

[feanor]

so it's a damaged ram problem right ?

[feanor]

i checked my shutdown-reboot logs , server not shutdowning . Its FREEZING and for get out from freezing need a reboot.

my host checked hardwares they said fine. today i found badchecksum logs in my kern.log but it was about 27015(Counter-Strike port) can it make freeze ?

Post "free -m" command run in the evening.

Also post "uname -a" at any time of day.

Why do you have 90mb swap?

[feanor]

how much should be ? i decreased processings , server didnt freeze anymore

[IzNoGoD]

I'd advise between 8 and 32gb swap

[kung foo man]

If you really run out of RAM, maybe just consider a better setup, since swap is slow as fuck

Or ye, kill unused "processings"

[feanor]

i decreased processing , my problem fixed. thx for you answers
