> As per our understanding camel picks up the file from the mentioned directory
> i.e in my case-stageDummy and processed by process-myProcess
> and moves it to .camel sub folder.We noticed that if we were having more than
> or around 1000 files in the folder -stageDummy ,there were some exceptions
> thrown
> This exception is thrown randomly for n number of files,where n changes
> everytime we execute our main.Note that we were not trying to access the
> exchange
> instead we kept our process simple.We could see that if there are 1000 files
> in our folder then the processor is getting called 1000+x times ,where x
> changes everytime example it gets called 1024 times,and we could see that
> camel is trying to process these x number of files again
> We are attaching the Sample Main class
