Mapper-parsing-exception in the bro-network index


I am having some difficulty where every so often I lose an index event due to a mapper-parsing-exception error. I am going to paste the error below this message. This is one error that I have come across, and I know I have seen a second one but will have to wait until I have copied it to show it. Sorry for the odd formatting but the log has it as one line so it copies kinda odd. My setup is a single node RockNSM that has everything installed except stenographer and docket. ISO is 2.4.2-1905.
