Hi @N8N_userN and @MutedJam
I’ve got a similar error. My self-hosted n8n is restarting every 3-5 minutes. And I also use the EmailReadImap node as a trigger. Actually, the error seems to origin there. This is my log that always looks like this before a restart:

Looking into the code, I cannot definitely say at what place the error happens, but it seems like there’s a uncaught promise rejection or something like that.
