The upgrade seemed to go OK, but when I start the master process it starts ctl_cyrusdb. I get the following messages:

and that's all. ctl_cyrusdb never seems to finish recovering, imapd never starts, etc.
We do have over 100G of email... Should ctl_cyrusdb take hours?
Take a look at your top output, and see if any IO or CPU activity is happening. If not, take a truss (Solaris) or strace (?) (Linux) of the ctl_cyrusdb process. Something that has been plagueing me is that ctl_cyrusdb runs out of filedescriptor because it opens the same file about 250 times. So if your truss output shows poll(), and EMFILE, that might be your problem.
If, and only if that is the case, you might be helped by removing the deliver-db, the tls_sessions db and all the snapshots. However, make sure you make backups first! I haven't yet had this problem again on 2.1.16, but I did the first time I started 2.1.16 using my 'old' databases.
Does anyone else experience the 'out of file descriptors (EMFILE)' problem?
