Server hangs out for ran out of the swap space.

[gral]

hello ev1;

for five day in a row my server hangs out ( i cant enter on it, but still with ping) because is ran out of the swap space always at the same time. Is a server with 2 Gb of ram and four 4 Gb of swap and only receive http request

Could be a memory problem, yesterday i disable the omm-killer what i saw it in the logs but with not luck, the server continue hangs every night.

I'll ask to the DC a change of the physicals mem .

Have anyone any idea to stop the hangs ?.

Thanks if you need futher information please let me know.

Regards! :D

how about setting a cron job to clean out the swap space and/or restart the httpd service.

hello chipsafts thanks for quickly answer but, in which way i can clean my swap memory ?

I have a cron already controlling the httpd process ?

Other way i was thought is limitds de httpd process in the /etc/security/limits.conf , could be good ? :confused:

Many thanks!

presuming your swap is called /tmp ,
at the command line do

ls -l /tmp | head -21

copy and paste the results in a reply. Seeing a subset of the files being created might help.

As far as i know my swap is a single partition; here is my /tmp output and added the df and fdisk -l output too.



root@server1 ~]# ls -la /tmp | head -21
