I already posted in #︱general , but I was now able reproduce the problem.
1. Add a new IMAP with around 500+ Emails 2. check cpu load 3. Twenty will become unresponsive
I currently use a VPS with 4GB RAM and 2vCPUs that 2 steps are able to make the vps completely unresponsive (no ssh login possible, twenty UI unresponsive, etc..) After an minute or two the server recovers or restarts because out of memory.
With a smaller Inbox (50-100Mails) it’s working and the synced status appear nearly instant.
