Hello, This was found with MINA 2.1.3. Is this a bug? I stumbled upon this while performing analysis of heap dumps of a JVMs that suffered from an issue where no user was able to establish a connection to our server software anymore.
Our application uses an ExecutorFilter. The OrderedThreadPoolExecutor of the affected server seems to be in an inconsistent state: - idleWorkers: 2 - waitingSessions.count: 2293 - workers.map.size: 0 I will attempt to include a screenshot of the profiler that holds more data (if the mailinglist allows me). What strikes me as odd is: - No workers, while there are sessions waiting to be processed - No workers, but a non-zero idle workers count Servers that are unaffected by the issue have an idle worker count that is equal to the amount of workers (I assume that the snapshots were taken when that server was not actively processing data). For reference: the issue that we are experiencing (possibly caused by this) is tracked in https://igniterealtime.atlassian.net/browse/OF-2367. Multiple people are reporting the issue, but I've been unable to reproduce it locally. Kind regards, Guus [image: image.png]
