Linux : RAM usage vs Swap

How Linux uses RAM (very simplified) Each application can use some of your memory. Linux uses all otherwise unoccupied memory (except for the last few Mb) as "cache". This includes the page cache, inode caches, etc. This is a good thing - it helps speed things up heaps. Both writing to disk and reading from disk can be sped up immensely by cache. Ideally, you have enough memory for all your applications, and you still have several hundred Mb left for cache. In this situation, as long as your applications don't increase their memory use and the system isn't struggling to get enough space for cache, there is no need for any swap. Once applications claim more RAM, it simply goes into some of the space that was used by cache, shrinking...

Disabling Core Dumps in cPanel

I recently found a (cPanel) server was generating over 100Gb of core dumps every time a bad PHP script died or Apache died.

Linux I usually do this on cPanel servers also, just to be double sure! 1. Disable core dumps for all users. Edit /etc/security/limits.conf and check that * hard core 0 exists 2. Disable core dumps for setuid programs echo 'fs.suid_dumpable = 0' >> /etc/sysctl.conf sysctl -p 3. Finally, set...
