I'm experiencing an issue when sometimes the memory gets 100% full, and the swap file also, and the server becomes non-responsive and has to be restarted (causing also problems in database). This is what Cacti shows:
The server is running a web-app (database + apache) and during that specific moment didn't experience any ir-regular traffic or usage.
I have a memory problem with my servers (Debian 6.0) where is installed Apache httpd 2.2, mod_php and APC.
Actually it seems that httpd allocate all available memory (4GB) when is waiting too much for an answer from Mongodb (30 seconds timeout).
hi.
i'm newbie in linux.gnome warns me that i don't have enough hard space.and when i look i see that i have a 5G swap memory.
and when i look at system monitor i see that linux almost never uses swap memory because i have 4g ram.and swap will be usefull while ram is full.
i want to decrease my swap memory and make it 3g.is it possible to decrease it and add the extra 1g to the root???
Take a look at this screenshot that I took after doing free -m: http://gyazo.com/aa54d264956e56acb99024e2374de0c0.png?1340387738
I notice that I have a ton of swap memory not being used, could I convert that to something that CAN be used? I'm sort of a noob with this, sorry if it's a stupid question.
Also, when doing top as outlined in Who is using the swap memory and why?
Hi,
I am not sure how many scripts / java processes running on my HP-UX server.
I need to calculate the total heap of these processes.
I then need to recommend increasing the swap memory to be increase and equal to total heap if that is the right concept.
Recently my friend told me that it is a good idea to turn of swap on linux webservers with enough memory. My server has 12 GB and currently uses 4GB (not counting cache and buffers) under peak load.
His argument was that in normal situation server will never use all of its RAM so the only way it can encounter OutOfMemory situation is due to some bug/ddos/etc.
I'm operating a little storage server on debian, over the past months I've noticed the process udisks-daemon eating up almost all available memory.
Is this just really aggressive caching or a memory leak?

Hi Experts,
Need your advise in determining the size of swap space in of the new HP-Ux server.
Server is having 32G of physical memory.
Ideally what amout of physical memory should be allocated as a swap space?
Following document from HP suggests to have minimum swap space equivalent to physical memory on the system.

I am confused i
I am running centos 5.8 with cpanel.
Lately I am getting reports that my swap is full , but there is a lot of free memory to use.
