Interbase crash after 64 connections

[Ivan A. Pereira]

My Interbase 7.5.1 and 2007 is crashing when I try the 64th connection. It
happens when I open an application (Delphi 7 win32) that makes 64
connections and when I open an application that makes 1 connection for 64
times. The interbase.log is:

SERVER (Server) Tue Jun 10 11:26:13 2008
INET/select_wait: select failed, errno = 10055

SERVER (Server) Tue Jun 10 11:26:13 2008
SRVR_multi_thread/RECEIVE: error on main_port, shutting down

This happens in some computers with Win 2003 Server and XP, and is note
related with ServicePack. In other computers with the same OS it is working
OK. So, it I think it depends on some hardware details, specially about
muiti-thread.

Does any one can help me ?

Try running the following from a command prompt, does it work?

for /L %i in (1,1,65) do start "%i" isql "path to your database" -u
sysdba -pass masterkey

If it works (and it does for me), it shows that 65 connections work. The
first step to resolving this issue is having us reproduce it in a simple
manner. So far, we do not know how to make it happen.
