Josh Berkus napsal(a):

However what happened? I think that following scenarios occurred.
Postmaster listen only in one process and there are many clients run
really parallel. T2000 server has 32 threads ( 8 core and each has 4
threads). These clients generate more TCP/IP request at one time, than
postmaster is able accepted.

I don't quite follow this ... are you saying that the regression test generate more than 128 connections? And that Solaris ships by default only allowing 128 connections?

My idea is completely wrong. The problem is not related to TCP/IP stack. It related only to UNIX_AF sockets. I have tried analyze problem with dtrace, but I cannot reproduce this on my machine. Josh could I have access to this server (for D-Trace I need root access as well).
