Just curious...how did you actually migrate the messages? Did you do it through
IMAP, or did you use some migration tool that manipulates the files directly? The
reason I ask is I'm wondering if the people that are having this problem have a
message or messages in their box that Cyrus doesn't like for some reason which
causes it to crash. I would think that if you migrated through IMAP this wouldn't
happen but if you used a tool that manipulates files directly then it might. Of
course I'm just guessing.
One thing to try: Create a subdirectory under /var/imap/log with the same name as
the user having the problem. Cyrus will create a telemetry log for that user which
will tell you exactly what is taking place in the IMAP conversation. If it is a
particular message that Cyrus is always dying on this should be able to tell you
which one it is (maybe?).
Just a thought...
