Additional Information

When the zenworks-inventorywebservice can't be reached in some cases the agent fails over to the zenworks-fileupload service.
 
One way to distinguish the bad requests from good ones is to determine which devices are sending too many active requests at a time.  This script shows ip addresses of inbound requests to identify possible candidates for the FTF (note those with > 200 inbound requests).
 
netstat -aln | grep -i ":81" | awk '{print $5}' | cut -d ':' -f1 | awk '{arr[$1]++} END {for(i in arr) printf "%6s %s\n", arr[i],i}' | sort
