Near as i can tell kmail2 with mboxes is a time bomb.  Eventually the size of
the mbox gets too big for the new infrastructure to handle and people will
start getting failures.  I've done a fair bit of testing and can't find a
consistent threshold for when problems start but the problems always start
eventually.  I've mostly had success up to about 500 messages in one file but
sometimes I can get up to 1000 messages before the error messages start (and
sometimes the flakiness happens before 500).  It might be more dependant on the
size of the file (attachments, etc) rather than the number of messages.

Seems the new infrastructure is WAY too precariously balanced and it's easy for
a big mbox file to bring the whole house of cards down.  The numerous layers of
complexity also make troubleshooting real difficult if not impossible.

I'm using a 500G spinning disk on a Core2 Quad 3.2Ghz machine with 4 gigs of
RAM.  I haven't tested on an SSD drive but I suspect a SSD will handle more
messages before the failures start but the failures will still happen
eventually.

Best bet seems to be considering MBOXes unsupported under the new
infrastructure and either convert all your folders to Maildirs or switch to
something like Thunderbird or Claws that handle large mbox folders reliably.

Kmail2 is definitely a step backwards.
