 Scott Long helped to fix this issue for me:
 
 "The difference between FreeBSD 9.x and 10 is that in 9.x, it ran in=20
 =93optimistic=94 mode, meaning that it didn=92t rely on getting receive=20
 messages from the switch, and only took a channel down if the link state=20
 went down. In strict mode, it looks for the receive messages and only=20
 transitions to a full operational state if it gets them. So while I know=20
 it=92s easy to point at the problem being FreeBSD 10, seeing as FreeBSD 9=
 =20
 worked for you, please check to make sure that your switch is set up=20
 correctly."
 
 Setting up my Juniper switch to "active" LACP mode it worked again:
 
 "The LACP mode can be active or passive. If the actor and partner are=20
 both in passive mode, they do not exchange LACP packets, which results=20
 in the aggregated Ethernet links not coming up. If either the actor or=20
 partner is active, they do exchange LACP packets. By default, LACP is=20
 turned off on aggregated Ethernet interfaces. If LACP is configured, it=20
 is in passive mode by default. To initiate transmission of LACP packets=20
 and response to LACP packets, you must configure LACP in active mode."
 
 If you have this issue please check if you have a similar setting.
