7.5: Fatal errors from eigrpd

Hello all,

I'm running eigrpd in a VMWare environment and after upgrading to 7.5 from 7.4 I'm noticing eigrpd is failing with a couple different errors.  In 7.4 and prior I never had any problems.

I tried to include everything that I thought might be relevant but if there's any other information I can provide please let me know.

Has anyone else come across anything similar?

Thanks,

Mark

examples:

test1# eigrpd -dv
startup
eigrp_if_start: lo1 as 1 family ipv4
eigrp_if_start: em0 as 1 family ipv4
if_join_ipv4_group: interface em0 addr 224.0.0.10

and

RouterTest# eigrpd -dv
startup
eigrp_if_start: em1 as 1 family ipv4
if_join_ipv4_group: interface em1 addr 224.0.0.10
rt_new: prefix 198.18.101.0/24

route_del: prefix 198.18.101.0/24 via connected

This is happening on two of two upgraded VMs.

(just in case)

I've tried with net.inet.tcp.tso=0 and net.inet.tcp.tso=1.  Same result.

The configs I'm running are pretty basic:
