quota on cyrus 2.2.12

[Ivan Synyeokov]

Hello,
after upgrading from 2.2.3 we are experiencing strange problems while
running quota -f. Actually it takes about a few hours to completely fix
all mailboxes and all this time randomly (I mean it's difficult to say
what user and when) users are getting overquota errors or quota reports
are going crazy. For ex.:

01:02 AM
user at mydomain
Report mailbox quota for user at mydomain
Quota  % Used    Used Root
10000       1     182 user.user at mydomain

02:03 AM
user at mydomain
Report mailbox quota for user at mydomain
Quota  % Used    Used Root
10000       0       0 user.user at mydomain


01:02 AM
user2 at mydomain
Report mailbox quota for user2 at mydomain
Quota  % Used    Used Root
100000      56   56300 user.user2 at mydomain

01:20 AM
user2 at mydomain
Report mailbox quota for user2 at mydomain
Quota  % Used    Used Root
100000      84   84450 user.user2 at mydomain

01:46 AM
user2 at mydomain
Report mailbox quota for user2 at mydomain
Quota  % Used    Used Root
100000     112  112600 user.user2 at mydomain

01:55 AM
user2 at mydomain
Report mailbox quota for user2 at mydomain
Quota  % Used    Used Root
100000      28   28150 user.user2 at mydomain

quota -f starts about 1:05AM, and it's useless to say that there were no
actual activity on selected mailboxes. :(
After quota fixing everything seems to be ok, until next time we run it.
So, my question is what reason could cause such a problem and the second
one (that's about why we are running quota fixing every night) is why
quotas breaks so frequent?

Below there is some tech info:
OS: FreeBSD 4.11-RELEASE
Cyrus: 2.2.12
db-4.2.52

from imapd.conf:
quotawarn: 90
lmtp_over_quota_perm_failure: yes
quota_db: quotalegacy
