Hi Dave,

Glad to hear that.

The accept is a TCP error.  It could complain about network buffer space
in the kernel maybe or file descriptor limits.
But 900 + 30 +30 + some extra is well within 1024 file descriptors ...
Also 30*8 TCP connections should be well within linux default capacity.

You could try to lower the
 	outgoing-num-tcp: 10
 	incoming-num-tcp: 10
But I have no clue why the errors are appearing.

At least it is being distributed better. That helps.

Well for fine-tuning; set the other *-slabs options to 8.
increase the infra structure cache size.

Best regards,
   Wouter
