Please wrap lines at 70 characters. This is on all the FreeBSD systems? This is really confusing I've _never_ heard of this happening, do you have any machines built with the same _exact_ hardware exibiting the same problems or not? Have you tried 4.0? Without some sample code this is going to be very hard to reproduce. Are you sure you aren't running out of process slots? What is maxusers set to in the kernel? How many processes typically run at the same time? -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
