Considering the parent is in sbwait, which is a network send, it appears to be waiting for network I/O. Why it would be doing network I/O, I don't know; I'd suggest tcpdump and/or ktrace. I don't know if dump is SIGIO based or not. -- Doug White | FreeBSD: The Power to Serve dwhite_at_gumbysoft.com | www.FreeBSD.orgReceived on Mon Mar 08 2004 - 17:18:26 UTC
