I don't know, but most IMAP connections are just idling, so it could be anything from 10-100x.

It's just imaptest. If it detects one connection stalling, it stops making new connections to the server until the stall goes away.
That's however a good way to detect what it is that's stalling. Just wait for a while until there are only stalled connections, and you can truss the imap connections to see what they're doing. Are they waiting for some locks?
