We are using zmq (2.2.0) with conjunction with openPgm (5.1.118) and we are experiencing an memory usage issue.
The memory usage seems to grow without bound. Trying to isolate the problem we set up an environment with only the server running. The server sends out a small heartbeat type of message every few seconds (5 for example). Monitoring the memory usage of the server it continue to rise even after hours of execution. Based on our measurement, the memory growth is about 600KB/hour, and continues to grow regardless how long it has been running. The following is what we have done in trying track this down: 1. Run our code through valgrind. It did not find any leaks. 2. If we switch PGM to using TCP, the memory growth seems to stop. 3. Set the socket rate (100000) and socket recovery ivl (10). We are stock and don't know what else to try. Any advise would be appreciated. Thanks, -leo
