Likely some service timing out because it's attempting to network related stuff.

Actually, I'm not seeing it in the Handbook or man pages but I only
took a quick look.  You either need to assign your addresses in
advance using the ifconfig_igb0_alias syntax shown in rc.conf(5) or
have them assigned at jail start time with this syntax.

jail_test_ip="igb0|67.xxx.xxx.xxx,igb0:2001:xxxx::xxxx"

It looks like this <interface>|<address> format is shown a little bit
later on in the Handbook.
