wrong. vmstat output looks weird:

???
Since you have a lot of cpu, could you "strace -f -T -o /tmp/nitz -p xyz" one
or two of your perl processes when they hang ?
If you do not have too many processes, monitoring "echo t > /proc/sysrq-trigger"
for some time could tell what the system is waiting for.
