Subject:   ps Causes Hard Hang
Message-ID:  <200403031721.i23HLUo9023985@cwsys.cwsent.com>

next in thread | raw e-mail | index | archive | help
I'm running 5 -CURRENT systems. My firewall system, using IPF, hard hangs 
every time ps is entered -- totally unresponsive, requiring either a power 
cycle or reset switch to bring it back to life.

Before I start digging into this seriously I'd like to possibly get info 
from anyone who may have experienced this before.
