Here is the requested details regarding the psql.exe problem. There is difference in how non-blocking socket connects (i.e. using fcntl to set O_NONBLOCK) are handled in 1.1.4 and 1.1.5-3. Specifically, in 1.1.4 connect returns 0, while in 1.1.5-3 connect returns -1 with errno set to EAGAIN (i.e. No more processes). BTW, by reading the Solaris man page for connect, 1.1.4 may not have got it quite right either. connect should return -1 with errno set to EINPROGRESS for non-blocking connects that cannot be established immediately. Attached is code to duplicate the problem. Try running the client on a 1.1.5-3 machine, the server can run on any machine: $ server -p 13131& $ client -h <YourServerHostName> -p 13131 Jason -- Jason Tishler Director, Software Engineering Phone: +1 (732) 264-8770 x235 Dot Hill Systems Corporation Fax: +1 (732) 264-8798 82 Bethany Road, Suite 7 Email: Jason.Tishler@dothill.com Hazlet, NJ 07730 USA WWW: http://www.dothill.com
