"Logging to internal hitachi-leeds-int-leemon01 errors: 9346 dropped: 116128

"

Above output shows that you have setup a syslog server whose name is "hitachi-leeds-int-leemon01 ".While sending syslogs to this server,packets were dropped.This essentially tells us that there is a communication issue between the server and f/w.It could be because of high traffic conditions where f/w tries to send the logs to server using the inside interface and because of high traffic passing through inside interface,syslogs get dropped.
