Sorry, I was in a hurry. It won't work even after a dovecot restart. I
must delete expire's database directory, which I set with "expire =
db:/var/dovecot/expire/expire.db" under the dict {} section. Then after
a dovecot restart it works fine (at least for a couple of weeks).

[Dovecot] Error: dict: Failed to initialize dictionary 'expire'
Hi! Using dovecot-1.1.17, and BDB-4.6.21. I'm having this error in every two weeks or so. I've running this in a crontab: /usr/local/sbin/dovecot --exec-mail \ ext /usr/local/libexec/dovecot/expire-tool The expire plugin and tool is working fine, the configuration is ok, and I'm using the BDB backend. What happens in every ~two weeks is dovecot starts to give me this error messages: Error: dict: db_env: Unable to allocate memory for transaction detail Error: dict: Failed to initialize dictionary 'expire' Reading thru Oracle's Berkeley DB FAQ: http://www.oracle.com/technology/products/berkeley-db/faq/db_faq.html#28 "This error means the maximum number of active transactions configured for Berkeley DB has been reached [...] When all of the memory available in the database environment for transactions is in use, calls to being a transaction will fail until some active transactions complete. By default, the database environment is configured to support at least 20 active transactions." What could be happening here? Why coudn't it finish its transactions? After a dovecot restart it works fine :\ Thanks in advance for any hints. Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1
Re: [Dovecot] Apple patches 6-8
If you start renaming API functions, rename all of them for consistency. :) Agreed, but when changing code on a branch, minimizing code deltas makes merging easier. Your code disabled idle timeout entirely Yeah, probably not a good idea. If I had realized that I probably would have just dropped the connection after N failed auth attempts, and chosen N for when it matched the idle timeout. Your solution of clamping the backoff to just under the idle timeout is fine too. PS -- Today is busy so I'll try to submit the next patches Monday or Tuesday.
[Dovecot] Heartbeat OCF ressource agent
Hello,
I've tried to write an OCF ressource agent in order to manage by the
heartbeat way a dovecot server. It seems to work fine.
This kind of script could be found in the directory on a CentOS release
5.2 :
/usr/lib/ocf/resource.d/
If the attachement isn't working, I've cut and paste the script here :
