I am getting issues like no free memory
I am trying to find how to and from where can i delete the contents from the tmpfs
I tried restarting the machine which did not help.


df -kh
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 39G 20G 17G 55% /
/dev/sda3 186G 175G 1.4G 100% /rhel5pdi
tmpfs 755M 0 755M 0% /dev/shm




Thanks

James,

As per your logs your tmpfs is 100% free and that is maintained automatically by OS and if sometimes it is full, restart can do the needful. Restart clears everything in tmpfs.

As per your output it is /dev/sda3 186G 175G 1.4G 100% /rhel5pdi which seems to be culprit.

I'm not sure how RedHat manages memory, but afaik, tmpfs is something different from swap, and for free memory you need, if something from an harddrive, then swap.

Swap isn't measured and reported with df but with 'free':

To search for your swap space, you may use fdisk -l with sudo (sda3 on my system):
