[Bro] successful_RPC_reply_to_invalid_request and ContentGap

[bchen at cs.ucf.edu]

Hi everyone,
   I used Bro to read a trace file that was captured from a local network. In
Bro's log files, the majority of log records are about
successful_RPC_reply_to_invalid_request and ContentGap. What situations can
cause these two alerts?

thanks
