Maria Petridean updated DIRMINA-1039:
-------------------------------------
Remaining Estimate: (was: 2h)
Original Estimate: (was: 2h)
> Response messages queue up on the server side waiting to be written to
> socket, while the server continues to read more request messages, causing out
> of heap memory

> Key: DIRMINA-1039
> URL: https://issues.apache.org/jira/browse/DIRMINA-1039
> Project: MINA
> Issue Type: Bug
> Components: Core
> Reporter: Maria Petridean
>
> One case in which this bug reproduces is by using a client which generates a
> heavy request-load. The mina thread which processes both reads and writes -
> exits the write cycle after processing every empty marker (the WriteRequest
> which wraps an empty buffer, acting as a message marker). This will result in
> the thread resuming the read cycle, hence reading more client request
> messages. After a few minutes, the number of read messages is much larger
> than the number of written response messages, even though the responses are
> waiting in the queue, ready to be written to socket.
> To solve this, the sever shouldn't exit the write cycle after processing
> every marker WriteRequest. This way the ratio between the read and written
> messages will be more balanced; this will avoid the heap memory getting full
> and causing server degradation.
> Also, an improvement can be considered here to avoid using the same single
> thread for both reads and writes.
