There are problems with the threads library in -stable. These have largely been addressed in -current, but there are a still a couple of known problems remaining. I have a patch at: http://people.freebsd.org/~deischen/libc_r.diffs-stable that merges the threads from -current into -stable. Please try this and see if it fixes your problem. I hope to update this patch with some more changes, so check back again in a couple of days. These changes are not going to make it into 4.2-RELEASE. I will keep the patch file above updated with whatever changes make it into -current, and MFC when I have adequate feedback that they don't break anything that currently works. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
