It's not that easy. The server becomes extremely unstable under these conditions.
I tried to build the kernel with '-g' option and included 'dumpdev' in /etc/rc.conf. The server can't even make a memory dump: it either gets one more page fault or just stops responding to anything but Reset key in the beginning of the dump.
It's strange since it rebooted well while the kernel was built without debugging symbols and a dumpdev. Any ideas how I can make a memory dump?
