- 6What makes you think you need to? Linux has pretty good memory management, it should be able to do this on a need-to-do basis.terdon– terdon ♦2014-06-27 18:05:52 +00:00Commented Jun 27, 2014 at 18:05
- 16Note that freeing up memory like this is used to make the machine go slower, not faster. Its if you want to benchmark something on a cold cache.derobert– derobert2014-06-27 18:14:41 +00:00Commented Jun 27, 2014 at 18:14
- I have a Java process eating all of my 24GB RAM. I can't terminate it. I don't know how to open a little space for other processes?Mohsen– Mohsen2014-06-27 18:37:48 +00:00Commented Jun 27, 2014 at 18:37

- 3@Mohsen, If the java process has already eaten up all of your ram, chances are that the kernel has already dropped all caches to give more memory to java. Purging, or dropping caches, won't give you any more free memory of a process has already demanded all of it.daboross– daboross2014-06-27 23:00:57 +00:00Commented Jun 27, 2014 at 23:00

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
