Oh wow ... according to this, I have: mars# wc -l /tmp/output 11238 /tmp/output (minus some header lines) sockets running righ tnow ... okay, next question ... under 'Active UNIX domain sockets, I see alot that have no Addr: Active UNIX domain sockets Address Type Recv-Q Send-Q Inode Conn Refs Nextref Addr d06b7480 stream 0 0 0 c969b240 0 0 private/proxymap c969b240 stream 0 0 0 d06b7480 0 0 ce6fc870 stream 0 0 0 cf744870 0 0 private/rewrite cf744870 stream 0 0 0 ce6fc870 0 0 ce4b2630 stream 0 0 0 d0cee900 0 0 private/proxymap d0cee900 stream 0 0 0 ce4b2630 0 0 d0437240 stream 0 0 0 cf716000 0 0 private/proxymap cf716000 stream 0 0 0 d0437240 0 0 c94f4990 stream 0 0 0 cee6ed80 0 0 private/rewrite cee6ed80 stream 0 0 0 c94f4990 0 0 d0cefcf0 stream 0 0 0 cb281a20 0 0 private/rewrite cb281a20 stream 0 0 0 d0cefcf0 0 0 ce0d5240 stream 0 0 0 cb251480 0 0 private/anvil Now, the 'Conn' field from the previous line matches the 'Address' line of the 'blank Addr' ... so there are two sockets for each Addr? in vs out? To give reference point ... mars above has 91 jail'd environments running on it, its been up 2days, 9hrs now, and has 11k sockets in use ... Hrmmm ... just checked jupiter, and she has 32 jail with 1080 sockets ... venus has 62 jail with 2819 sockets ... and pluto has 35 jails with 1818 sockets ... mars is running on average 2x the number of sockets per jail then the other servers ... Is this normal? mars# grep d067f900 /tmp/output d067f900 stream 0 0 0 cafd4c60 0 0 cafd4c60 stream 0 0 0 d067f900 0 0 There is no 'Addr' related to either of them? I can scroll down pages and pages of those types of entries, that don't have any Addr field associated with them ... > > -- > John-Mark Gurney Voice: +1 415 225 5579 > > "All that I will do, has been done, All that I have, has not." > _______________________________________________ > freebsd-stable@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org" - ---- Marc G.
