Issue: 

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

When more information is needed to investigate an issue, create a "strace" log as follows?

In Ubunu and SLES Linux Environment: 

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
4. Reproduce the error
5. send /tmp/strace.txt
