0 Swap space and httpd crashing

[TapanB]

Hello,

My server from today is not working properly. The httpd service is crashing and giving some timeout error. Also when i login to WHM then i see in the stats that Swap Space is being used 0.00 only.

Are these 2 things linked ? I am hosting 400 sites so why swap space wouldbe 0.00 ?

I am not getting it. Nothing was changed and the server was fine but today onwards its just not working properly.

Please suggest.

Thanks.

You should NOT be using swap space on a regular basis. Swap is reserved memory space on-disk for times when the system overruns it's available physical memory (RAM). This should only happen rarely, as swap access is orders of magnitude slower than RAM access. Thus, having zero swap usage is actually a GOOD thing.

You should be checking your Apache error_log for reasons as to why your webserver is hanging/crashing.
