To create a trace log use the Linux "strace" command to trace system calls and signals.

  1. sudo apt-get install strace
  2. ps ax | grep win4cdahubd (find its pid)
  3. sudo strace -fp <pid-from-step-2> >/tmp/strace.txt 2>&1
  4. Reproduce the error
  5. send /tmp/strace.txt

In RHEL and CentOS Linux Environment: 

  1. yum install strace
  2. ps ax | grep win4cdahubd (find its pid)
  3. strace -fp <pid-from-step-2> >/tmp/strace.txt 2>&1
