Hi I tried to get some logs: https://pastebin.com/Z8xVzpzW
As you can see the process isn't shutdown and still in transaction as long dovecot is running. It destroyed the transaction when I stopped Dovecot. And this behavior only happens when the mailbox of user is full... Any Ideas how to debug this correctly? > So far, I haven't been able to reproduce anything weird at this end. > Can you provide: > > - Output from `dovecot -n' > - Protocol logs from the connections between Exim and Dovecot > director/proxy and between Dovecot director/proxy and Dovecot backend > (e.g. using ngrep when connections are plaintext or using the rawlog > facility). > - Dovecot debug logs produced with `log_debug=category:lmtp' for both > director/proxy and backend > > Regards, > > Stephan. > >
