on a ZFS file system. Every once in a while, a simple OS command like "ls -al" in a directory with 10-20 files will hang for more than 1 minute. I was able to use the truss command to finally capture one of the incidents where the "ls -al" command took over 1 minute. The unfortunate thing is that the truss output wasn't able to capture where the wait occurred. I am now moving on to dtrace - but wow...I am really hoping that someone on the list has had prior
