After about a year of being a member of the community I am now Stack Overflow Valued Associate #9 (Or Server Fault Valued Associate #1 if you like).

Besides trying to keep these sites up I will also be writing posts for the [Server Fault Blog][2].

comment centos + php leak memory, but where?
@AndreaSica: Re MySQL. I'm not positive, but I don't think MySQL would be cache, I would think it memmaps the the database files so it has more control. Higher level languages like PHP will be allocating memory with things like malloc(), they just do it for you. How about a screenshot of top + free -m output for each the following: 1) After a reboot and before your script has run 2) While your script is running, and 3) After your script has completed

@Isaac: Also netstat, if they won't let you have netstat you might want to start searching the job market before you go nuts ;-)

comment How does vm.overcommit_memory work?
@MikhailMorfikov: Yes, practically I think 0 makes the most sense. In my environment, the only time I enable 1 is for Redis, which does stuff where it expects do be asking for a lot more memory that it is using due to a fork(). The child will pretty much use all the same memory pages, but Linux doesn't know that says to be safe it has to assume 2x memory will be used (if you want to learn more: redis.io/topics/faq)

comment How does vm.overcommit_memory work?
@MikhailMorfikov: In theory, I believe so, but who knows what these programs are doing. Would want to see a more controlled environment with a simple program that just allocates say a gig of ram via Malloc. And then run the test after rebooting between tests.
