Having user with thousands of messages blocks the entire server after 2/3 messages and slow down agent reply

[Sapessii]

Describe the bug
As the title suggests, when a user with almost ~2k messages sends a message, after 2/3 agent replies the entire server is stuck, no error, no logs, nothing.
Neither the health endpoint can be reached.

Attached to this, a single reply for these users takes more than 1 minute (compared to the 10/15 seconds of a new user with no message history)

Please let me know if you need further details.

Hi! Sorry you are having this issue.

This is kind of hard to reproduce on our end - does this only happen at a specific number of messages?

Hi @mattzh72, unfortunately we don’t have a clear answer on that.

It looks like the issue isn’t tied to the number of messages but rather to a high number of passages for the agent.

In fact, the error logs reference the agent_passages table. You might try adding several hundred entries to that table and see what happens.
