The dovecot lda panics with "Trying to sync mailbox INBOX with open transactions" if a user has no sieve script defined. Debugging shows:

Sep 14 19:49:26 server dovecot: [ID 583609 local0.debug] lda(userxx):

I then did create an empty sieve script file with touch /home/grp/userxx/.dovecot.sieve and after that lda worked:

Sep 14 19:50:55 server dovecot: [ID 583609 local0.debug] lda(userxx):

I think the lda worked in previous releases without a sieve script
file in the users home directory.

dovecot -n output is:
