Hi,
Thank you for pointing me about -xc99 flag, I have compiled and
installed dovecot inplace of version 1.0.5 without any special actions
on the upgrade. And after starting it immediately got in it's log file
messages like:
---

index cache file
/var/spool/imap/seriv/.imap/.git-altlinux-ru/dovecot.index.cache:
Invalid argument

I have tried to delete dovecot.index.cache files from imap directories,
but this did not helped:

One more problem is with fd limit: I have a small dovecot installation,
so don't want to increase fd limit. I tried to decreasee
max_mail_processes, login_max_processes_count and login_max_connections,
but still I have

So I reverted to 1.0.5 which works fine for me.
