Redis Tracker Store fails to save data

Rasa Open Source

Hi, I keep getting this error, quite frequently on our Rasa Chatbot.

Error happened when trying to save conversation tracker to ‘RedisTrackerStore’. Falling back to use the ‘InMemoryTrackerStore’. Please investigate the following error: Extra data: line 18760 column 6 (char 510585).

We are using a load balancer which directs the request to two application servers. Redis is being used as locker/tracker store. Whenever we restart the API, the problem gets resolved. However we are doing load testing where multiple requests come from multiple users and this error quite frequently pops up while doing that.

have you checked the size of your Redis DB, sounds to me that your Redis is filled up, upon restarting it dumps the data and you have space again.

Hi Souvik,

I thought of the same. But I am not sure where to look for. I was looking for dump.rdb file in folder where Redis is installed.
