Description

This bug is reproducible (I got this 4 times within one hour), when "tcplay -i -d /dev/da8" is used and then I open up "mutt" (I guess any SSL connection would trigger the bug):

/var/crash # vmstat -M vmcore.0 -N kern.0 -m | grep " crypto "
Type Count MemUse SlabUse Limit Requests
crypto 2.63M 756M 0 756M 5.25M
