Understanding - too many open files


Staff member
Every operating system only allows for a certain number of open files/handles/sockets. Some web hosts have this limit set very low in order to get you off their shared web hosting to a more expensive VPS plan.

You can use the following terminal command to see what your setting is:

ulimit -n

Normally you will see a very high number. However some web hosts have this number set to for example 60 on their shared plans in order to force the customer into a more expensive plan.
