Same problem. Ssh-tunnel connection is also disrupted
with HZ=100. May I conclude that the HZ value is not
the culprit? Or should I try once again with HZ=10?

kern.ipc.nmbclusters is 4928 for this PC.
Is that good or bad?

"sysctl -a | grep -i polling" gives following:
kern.polling.burst: 150
kern.polling.each_burst: 5
kern.polling.burst_max: 150
kern.polling.idle_poll: 0
kern.polling.poll_in_trap: 0
kern.polling.user_frac: 50
kern.polling.reg_frac: 20
kern.polling.short_ticks: 0
kern.polling.lost_polls: 6
kern.polling.pending_polls: 0
kern.polling.residual_burst: 0
kern.polling.handlers: 0
kern.polling.enable: 0
kern.polling.phase: 0

I actually doubt whether the default values of
these sysctl variables would cause the problem.

Rob.
