there must be a memory leak #113

Closed Marwe closed 7 years ago

Marwe commented 7 years ago

mqtt-spy is eating memory faster than you can produce chips. In the attachment you can see the memory consumption logged in mqtt-spy via MQTT. Only few minutes and all memory is used up.

Same thing observed with these versions: mqtt-spy-0.5.3-jar-with-dependencies.jar mqtt-spy-0.6.0-beta-b56-jar-with-dependencies.jar

I published the memory usage with this bash snippet: while true ; do mosquitto_pub -t 'mqtt-spy/memoryusage' -m "$(ps -C "java -jar /path/to/mqtt-spy-0.6.0-beta-b56-jar-with-dependencies.jar" -o vsz=)"; sleep 1; done

Maybe someone observes the same and has the possibility to track it down?

Thanks

The amount of different messages was roughly 20 in total with 1 Hz (10 messages/second), one value being plotted.
