[quagga-users 12435] Software caused connection abort

Hi,
I have running
FreeBSD 8.2-STABLE #0: Tue Aug 30 13:48:54 CEST 2011
with Quagga 0.99.18

BGPD is configured as RouteServer, so we have about 120 IPv4 neighbors 
and 80 IPv6 neighbors
bgpd.conf file size is about 12MB

IPv6 is running well, but on IPv4 i got these errors.

this one on startup:
Aug 30 17:29:03 rs1 bgpd[6830]: BGPd 0.99.18 starting: vty at 2605, 
bgp@<all>:179
Aug 30 17:29:03 rs1 bgpd[6830]: [Error] BGP socket accept failed 
(Software caused connection abort)
Aug 30 17:29:03 rs1 last message repeated 4 times

and these after about one minute
Aug 30 17:30:21 rs1 bgpd[6830]: 91.210.16.219 [Error] bgp_read_packet 
error: Operation timed out
Aug 30 17:30:22 rs1 bgpd[6830]: 91.210.16.143 [Error] bgp_read_packet 
error: Operation timed out
Aug 30 17:30:22 rs1 bgpd[6830]: 91.210.16.42 [Error] bgp_read_packet 
error: Operation timed out
Aug 30 17:30:22 rs1 bgpd[6830]: 91.210.16.101 [Error] bgp_read_packet 
error: Operation timed out
Aug 30 17:30:23 rs1 bgpd[6830]: 91.210.16.181 [Error] bgp_read_packet 
error: Operation timed out
....


There are about 4 sessions of IPv4 established, but all other fail with 
erros above ...
I have tried 0.99.17 too, but the same result.

Have anyone idea what should be wrong?
Some system resources tuning would help?

On FreeBSD 7.0-RELEASE with 0.99.17 was all runing well.

Thanks for help
Jiri
