Pixelartist commented on issue #6427: State Functions - stuck after 3 events?
URL: https://github.com/apache/pulsar/issues/6427#issuecomment-593300264
Hello,
I reproduced the problem once more - with the following output within the log files:
logs/pulsar-standalone.log - empty
tmp/functions/public/default/StateMe/StateMe-0.log - [StateMe-0.log](https://github.com/apache/pulsar/files/4274256/StateMe-0.log)
Please see below - _input_ has more messages than _output_ where java shows a lot of io-errors during restart.
running: `bin/pulsar-admin functions status --tenant public --namespace default --name StateMe`
