quota -f doubling users' quota usage

[Jack Neely]

Folks,

I'm in the midst of upgrading our cyrus imap servers.  We've hit a snag
that our testing did not reveal.  The quota -f utility is doubling all
of our users' actual usage.  This seems to be reported several times on
various places on the web.  Running quota -f a second time seems to
correct the issue.  However, I wanted to track down the actual issue/bug
here.

We are moving from RHEL 3 i386 with Cyrus version 2.2.12 to RHEL 5
x86_64 machines running cyrus version 2.3.14.  We tar up the cyrus data
store and move it to the new server, rebuild the DB from a dump from the
old server, run reconstructs, and finally run quota -f.  We are getting
output below.

user.cechafin.RESTORE.Drafts: quota root user.cechafin.RESTORE --> user.cechafin 
user.cechafin.RESTORE.Sent: quota root user.cechafin.RESTORE --> user.cechafin  
user.cechafin.RESTORE.Sent.2006: quota root user.cechafin.RESTORE --> user.cechafi
user.cechafin.RESTORE.Sent.2007: quota root user.cechafin.RESTORE --> user.cechafin
user.cechafin: usage was 33900479, now 33914622
user.mmorrow: usage was 152034181, now 105570337
user.vrtownse: usage was 9382963, now 9385921
user.wwang: usage was 203145147, now 203333738
user.aaardest: usage was 31204975, now 62409950
user.aaaskar: usage was 44789845, now 89579690
user.aaatiq: usage was 29105529, now 58211058

What's happening?
