o Start a tcpdump on the affected systems:
-#tcpdump -s 0 -n host <ipaddress> > -w /tmp/$(hostname)-$(date +"%Y-%m-%d-%H-%M-%S").pcap &
o Gather an strace of a command that easily reproduces this issue, such as a 'cd' or ls of the directory in question:
-#strace -fvttTyyx -s 1024 -o /tmp/$(hostname)-strace.out <insert command here to reproduce the issue>
o Once the strace returns an error, stop the tcpdump:
-#killall tcpdump
-#tcpdump -s 0 -n host <ipaddress> > -w /tmp/$(hostname)-$(date +"%Y-%m-%d-%H-%M-%S").pcap &
