Re: Weird throttling since midnight

By Bill Cole at 05/26/2013 - 12:09

Do you have a Postfix queue named " "? Why does your Postfix config
think that you do, and that it needs hashing?

I'm not 100% sure that's your problem, but it seems worth fixing *AND*
figuring out how such an oddity made it into your config. If correcting
that is not a fix, you should recreate (i.e.postmap) all of the hash and
btree maps mentioned in your postconf output, after making sure that
postmap and all the other parts of Postfix are linked with the same
version of BDB

Also:

Whatever on that machine created random "gmon.out" files in queue
directories should be removed.

The Doctor:
Has your Berkeley DB library been updated? Perhaps you can revert
the update.

Apparently, their set_cachesize() function now returns an error
when Postfix sets the cache size.

This code has not changed since Postfix 2.0, more than 10 years ago:

if ((errno = db->set_cachesize(db, 0, dict_db_cache_size, 0)) != 0)
msg_fatal("set DB cache size %d: %m", dict_db_cache_size);

131072 (128 kbyte) is the Postfix default read buffer size:

berkeley_db_read_buffer_size = 131072

There is a similar parameter for writing, used in postmap.

None of this has changed since Postfix 2.0.

The Doctor:
That is the same Berkeley DB error. You can stop posting these now.
You may make more progress if you can back out the "improved"
Berkeley DB library.

You may also play with berkeley_db_read_buffer_size. The Berkeley
DB documentation promises that they accept buffer sizes of 20kB or
more, and their default is 256kB. If someone has screwed up Berkeley
DB, then perhaps it helps to specify berkeley_db_read_buffer_size
of 262144 (262144 = 256*1024). Hopefully they still accept that.

The Doctor articulated:

I have that version installed on a FreeBSD-8.3 system and it is working
fine. OpenSSL 1.0.1e is also installed if that makes any difference. It
is working with Postfix (2.11-20130405). All are from the FreeBSD ports
tree.
