Hi All,
I am working on Ubuntu 8.04.3 OS, with this I am getting a problem, Daily my server is down on same time at 4:00 PM
I seems server is down by "kswapd0" process, I am not sure,
As I run top command, I got below out put
I don't know much about servers, but the output above shows clearly that your memory and swap are completely full. And kswapd is the kernel swap daemon, which is probably just trying to deal with the lack of memory.
Well you're load avgs are extremely high, and, as noted, both your RAM and your swap partition are completely full.
You seem to have about 1.7Gb oRAM and 1GB swap (approx). I'd want swap at least as large as RAM on a server.
However, that won't solve your problem, you need look at what those processes are doing; probably start with Apache/PHP.
One of your running apps is eating your memory and then your swap. What is happening is that sometime your machine tries to get rid of all that trash. You need to monitor which one is doing this
Well, as others have pointed out - you're very short on RAM; but
you ALSO have the problem of 49.6%st ... the hypervisor chooses
to run something else instead of your guests half the time.
Those facts together (not enough actual grunt from the hypervisor,
plus massive memory constraints) to me explain the load satisfactorily ;}
