I have limited information at the moment (currently distracted by other projects) but I'm hoping that someone has already found and solved this problem.
I have a v1.2.1 installed on my development box waiting for me to tinker with the configuration. On several occasions, I have noticed that all the dovecot processes are listed as "defunct". I don't recall seeing anything significant in the logs the last time I checked. The system is not under any load.
Has anyone else encountered this before? If not, I will dig deeper. BTW, ignore the fd limit warning below; limits are set in the init script.
