SGD 4.2 - How to Tune OS to allow more file descriptors per process

We have started getting this error in our array and have to stop and start the server to allow users to login. Here is the error taken from stderrout.log.

Tune your operating system to allow more file descriptors per process.

Any ideas on how to tune the os to allow more descriptors per process?

Can you please state which operating system you are using. Since changing the amount of available filedescriptors depends on the OS.

I found the "Tuning" section in the array manager and was able to change the "File Descriptors" value to 8192.We'll reboot the servers and see if that works.

You have to change the max fike-descriptors on you OS as well.Perform the follwing commands as root:echo 64000 > /proc/sys/fs/file-maxulimit -n 64000To make these settings reboot proof add these lines to rc.local
