I don't know, but most IMAP connections are just idling, so it could
be anything from 10-100x.
- I'm concerned by the N/M number at the end of the imaptest10
output lines plummeting whenever one process goes into this stalled
state: it almost suggests as if the only thing the other processes can
do is logout? Are other sessions really being blocked, or is it just imaptest10 behaving like this?
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?
