## Rasa server 500 concurrent users

[@darich10](https://forum.rasa.com/u/darich10), thanks for the helpful post. We have productionised our chatbot on a single vm, it had no issues for less than 200 users. But now since the number of users have spiked to 500+, there is a lot of delay in the bot’s respons (>1min), and usually this delay is backed up by the below error

[rasa.core.lock_store.LockError: Could not acquire lock for conversation_id](https://forum.rasa.com/t/rasa-core-lock-store-lockerror-could-not-acquire-lock-for-conversation-id/30270/3)

Hi, I am also getting the exactly same error as yours, please can you confirm what worked in your case.
