Yes, that fixed 'too many files'.
I get quite often these messages:

14-Jul-2008 14:02:35.959 general: socket.c:523: unexpected error:
14-Jul-2008 14:02:35.959 general: socket.c:523: unexpected error:
14-Jul-2008 14:02:35.959 general: epoll_ctl(DEL), 398: Bad file descriptor
14-Jul-2008 14:02:35.959 general: epoll_ctl(DEL), 398: Bad file descriptor

On another machine under lower query load happens nothing like this.

Why happens this and how serious is the resulting impact?


Best regards
