Hi!
Yes, of course. It has nothing to do with Innobase.
Alex, you ran out of filedescriptors or out of anodes, depending on OS
that you are using.
It could also be caused by a bug in TCP/IP part of the kernel, but the
above causes are much more likely.
Check out both your global and ulimit values.
Regards,
Sinisa
