Weird behavior under FreeBSD

[Jiří Kubíček]

Hello,

OK. I can try to downgrade one of the machines if it should happen regulary.

My machine is:

FreeBSD blade5.sh.x 8.1-RELEASE FreeBSD 8.1-RELEASE #0: Mon Jul 19 02:36:49 UTC 2010     root at mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

The other one has custom kernel (GENERIC with IPSEC + TCP_SIGNATURE enabled).

>> Load of the machine jumps to 2.00 and birdc respond's very slowly. It takes minutes to "display protocols" and it becomes worse and worse.
> The CPU was 100% busy? In kernel or in userspace (BIRD)? (see 'top')

I still had top output in history:

last pid: 76966;  load averages:  2.00,  2.00,  2.00                                                                                                                up 3+09:57:45  12:01:27
64 processes:  2 running, 62 sleeping
CPU:  0.0% user,  0.0% nice, 25.2% system,  0.0% interrupt, 74.8% idle
Mem: 77M Active, 56M Inact, 366M Wired, 292K Cache, 418M Buf, 3445M Free
Swap: 4096M Total, 4096M Free

Yes. Today one of the machines was 1.2.3 and the other one was 1.2.4. Upgrading 1.2.3 to 1.2.4 didn't help, I still had to reboot the machine to get bird with kernel1 protocol enabled working.

Nothing in /var/log/messages and nothing in bird's log file.
