The following information describes the pdump tool, its options and uses.

Purpose

Extracts and gathers information from a running process

Using the script

Step 1. Determine what process is hung.

If you suspect a process is hung, first find its <pid#> using the ps command. Then, using proctree <pid#> , check if that process has child processes that it might be waiting on. If the parent process is waiting on a child process, then you should first try running pdump.sh on the last child found in the proctree.

Step 2. Run pdump on the process.

pdump.sh <pid#>
Where <pid#> is the process id that is suspected to be hung or looping.

If you cannot determine which specific process is hung, you may simply run pdump.sh against PID 1 (the init process) as a start point for investigation
pdump.sh 1
