Every since I have upgraded to 10.0-RELEASE I'm facing the following problem: I'm running various services (http, imap, smtp etc.) in different jail. As i have only one public IPv4 address I redirect the relevant ports to the jails and NAT connections from jails. After 2-3 days uptime all the TCP connections that are redirected by PF to jails are randomly dropped. The only way I can fix this is by restarting the server, as I cannot remove the pf.ko kernel module. This setup was working fine till 10.0-RELEASE, i.e. I've been using the machine with the very same setup every since 7.0-RELEASE. after a little bit of search I found out that I'm not the only one who's facing this problem: http://lists.freebsd.org/pipermail/freebsd-net/2014-February/037749.html
FYI: this bug has been fixed in 10.1-RELEASE
I there any patch for FreeBSD 10.0-RELEASE ?
