With both the GENERIC kernel and a custom kernel, the system hangs tight when more than about 256 filesystems are mounted. I've tested this with loopback NFS mounts, remote NFS mounts, and local NULL mounts. The machine freezes, responds to pings and changing of virtual console, but accepts no input. No errors are written to /var/log or console. A hard reset is the only way out, CTRL-ALT-DEL doesn't work. Please tell me what other info we can provide. This should be easy to reproduce, though I'd be happy to give anyone the perl scripts we use to tickle the bug. -Troy Cobb VP/CTO Circle Net, Inc. http://www.circle.net 1-800-321-2237 x308 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
