Looking at huge "MemUse" values for secasvar and ipsec-misc,
I suspect some kind of memory leak.

FreeBSD 11.1 has new IPSEC implementation and you may consider trying new version.

Meantime, you can try to flush all IPSEC-related data from the system:

service racoon stop
setkey -F; setkey -FP
service racoon start

If that does not help, reboot and start monitoring these numbers for secasvar and ipsec-misc.

How many IPSEC tunnells/associations do you have simultaneously?
And again, are those systems 32 bit or 64 bit?
