Well, this is rather embarrassing. I just looked through my .sh_history file and found that I never included the "-d -D" option for my truss command. I was building a script to run and never ran the script when the problem surfaced...I ran the command by hand and forgot the options. Now I have to hope I can catch the system hanging again... Here is what the output looks like when I run it properly... <server_name>:XXX02/xxx02/data00/oracle/local>more bill2.out Base time stamp: 1323649536.7395 [ Sun Dec 11 19:25:36 EST 2011 ]

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
Please share the truss output.
You can use http://pastebin.com<http://pastebin.com/fmtGg5rM> to share it.
