@gonejack try to increase the maximum open files. That value is pretty low.

[gonejack]

I don't think so, it's system default of brand new installation, could you check if there unclosed file leaks in memory?

[MikeMcQuaid]

We've not had any other reports here. Your system defaults may need tweaked.
