A few days ago my linux apache server ran out of memory. The server is a xen guest. The server killed all my processes except ssh.
A minute before it ran out of memory, a script of mine saved the output of various commands.
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 am using ubuntu 12.04LTS on my linode vps include core2 cpu, 2gb RAM. I am doing a lot of research on optimizing memory for mysql and apache process -> optimize apache memory use, there i am using two scripts for compute memory per process.
Our Linux server is responding very slow. Top command doesn’t show any excessive CPU usage. But I observe that even though there’s about 5GB free memory, system is using all of swap with no free swap left. Could this be reason for system running slow as in there being too many processes.
Running perl script in solaris 10 machine. Know the RAM Size is 25 GB. Have two queries.
Normally How much RAM memory a solaris process is allocated. Is it a default value assigned to any script or process. where it can be set? How do i determine how much max static array size can i have and how much dynamic memory can i allocate?
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.
hi all,
i have noticed that my server has 64 GB RAM and i have application in this server but the server has free memory only 15% and utilized 85% however it didn't eat from swap .
does any parameter can be configured in kernel to make the system clear memory from cache like linux
i found this command for linux and it worked it free the memory in redhat i want something like this in solaris ?
I have a shell script which sets some variables and then calls modules of a program in succession, one by one. Problem is that the script is executed on servers with many users, so sometimes the script starts running, runs for 10 minutes and then breaks due to lack of resources when other users run memory intensive processes.
dear all,
kindly i want to check my server memory utilization i used alot of commands but i want to make sure that it is acurate let me explain
i have a server which has 32GB RAM
Total Memory = 33423360 kb
Free Memory = 4172568 kb
Utilized Memory = 29250792 kb
Memory Utilization Percentage = 87.5 %
if Utilized Memory = 29250792 kb how can i make sure which processes eat this amount of memo
