I am not an advanced Linux user. I have a VPS with 768MB of RAM running CentOS.
I executed the
lsof command as root and I see that there is a list of 3000 files. Usually, how many files should be there? My system is getting very slow, so is this list too long?
How do I know which files to keep and which to close?
I have seen that there are multiple copies of the same files with different PIDs. There are many log files in the list that I have not opened. Is this normal?
