We have a linux server running fine in prod for weeks, until our user base started to grow and our java server started to fail in many places! It turns out that all files and sockets are failing because it is returning "too many files open". I believe I have reached some sort of file opened limits.
How can I change this? The ulimit command is showing "unlimited".
Any other ideas?
I believe this limit is per process? Because I can still open files with say, vi, for example...
Here is the full ulimit output
