        Hi,
such thing usually happens when GLib's GTask API causes starving of
threads by spawning subtasks, which create other GTask-s. This is known
(but somewhat ignored) GLib issues:

Four is not that many. I usually notice it when I have like 10 enabled
mail accounts (I have many more disabled).

Maybe routing/address resolution goes by different paths, returning
information in a timely manner. Or the hardware is different, causing
different thread interleaving, thus different processing of the tasks.

You can get a backtrace of the evolution in that state, to see what the
threads do. I'd goes it would be something about GNetworkAddress or
something like that (I do not recall the exact function name right now,
I'm sorry). You can get the backtrace with command like this:
   $ gdb --batch --ex "t a a bt" -pid=`pidof evolution` &>bt.txt
Please check the bt.txt for any private information, like passwords,
email address, server addresses,... I usually search for "pass" at
least (quotes for clarity only).

        Bye,
        Milan
