Interactive Brokers - IB _Gateway_ memory leak when subscribing to options

  1. I am very happy that IB actually found the culprit to this issue.

    The memory leak is caused by the gateway GUI logging. there are check-boxes on the gateway GUI, to show logs for API clients. It looks like this log window has unlimited buffer so all logs are kept from the beginning.

    So I guess the options subscriptions produces more logging, that accelerated the memory build up in the log window. Without enabling the logging, I have just run a test for 50 hours and no sign of any JVM memory build up yet. The OOM exceptions in the logs reported by the options model now appear to be just symptoms, not the cause.

    Well done IB.
