Comment 1 Jiri Skala 2011-05-04 19:37:04 UTC 
I'd like to ask you about working version. You've mentioned that quagga of F13 worked.
- which version of quagga of F13 worked
- does quagga-0.99.18-1.f13 work
- did you test quagga-0.99.18-1.fc14 as the first F14 version. What about downgraded version.

Thanks, Jiri
Comment 2 Łukasz Trąbiński 2011-05-05 14:59:46 UTC 
I have just found reason

[182496.068965] Out of memory: kill process 2383 (bgpd) score 7792 or a child
[182496.070133] Killed process 2383 (bgpd) vsz:2337840kB, anon-rss:463864kB, file-rss:88kB

It's look like FC14 (kernel, glibc) consumes/ need more RAM memory, anyway You can close this ticket.
