What Dovecot version? I did some improvements to this which aren't in
dovecot-stable releases yet. They can still happen with 1.0-alphas, but
should be pretty rare. They mostly happen if there are multiple
connections to same mailbox and one of the connections wakes up after
idling for a long time while there have been modifications to the
mailbox.

I have "if log file is lost, generate it from old and new index" in
TODO, but it probably won't make it into 1.0 release unless it actually
becomes a common problem.

You could also change the rotation values from
src/lib-index/mail-transaction-log-private.h. The defaults are that
if .log file is larger than 128kB and it was created more than 5 minutes
ago, it's safe to be rotated.
