linux out of vm virtual memory

You might think this is simple: you either have ram or you do not. But consider fork and exec with one large process replacing another. For a brief period, you have a lot of memory being requested, right?

No, it is not that simple. Read Minimizing Memory Usage for Creating Application Subprocesses for a deeper discussion.

Tools to look at memory can be confusing too. This thread details one persons problems with vm on early OS X.

VM = Virtual Memory. the kernel ran out of REAL and Virtual memory, and
processes were still demanding more.

To survive this, the kernel goes into lifesaver mode and begins "reaping"
processes somewhat randomly in order to free memory so that it won't crash.
(I think the only process safe from reaping is probably init).

How to fix it?
1> Don't run more on your system than memory will allow.
2> find the software with the memory leak, kill it, and upgrade to a version
without that leak...
3> Buy more memory or add another swap partition.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

I am a Kerio reseller. Articles here related to Kerio products reflect my honest opinion, but I do have an obvious interest in selling those products also.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
