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`
