[Dovecot] save failed to INBOX

Hello,

I'm seeing som error messages in the mail log, like this:

Jun 12 12:50:44 smtp2 deliver(user1@domain.tld): msgid=10784847.1181644475592.foo.bar@foo99: save failed to INBOX Jun 12 12:50:44 smtp2 deliver(user1@domain.tld): msgid=30757588.1181644556388.foo.bar@foo99: saved mail to INBOX

It seems that when two or more messages are being delivered at the same time, only one delivery succeeds.

Both the maildirs and the indexes are stored on a SAN ..

I'll try to read the source, to find out whether this is a locking problem. I would think that if a deliver -process finds that a maildir is locked, then it should wait, and retry?
