I have written a java input node to read files from a folder. Because the files are extremely large, I have to

.read them character by character, looking for a new line.

.After a number of lines I put the message to the rest of the flow which inserts the results into a database.

. when the input node gets control back it clears the message (msg.clearMessage).

. continues in this loop until all lines from the input node have been processed.

. when all processed, goes into a check-sleep-return-check-sleep-return loop waiting for more files to arrive in the folder.

I have noticed that while processing the input of a file, the memory utilization seems to grow and after a message is completely processed the size of memory used by the broker seems to stay large.

Does anyone know if this the way the broker works or should I look to my code or some function to release memory? (I think I am doing all the proper house keeping in the java code, and I thought that after a message was processed by a flow and put to a queue, the broker released the memory.)
