Its possible. I'm fairly certain that the code has been tested
successfully on 64-bit Solaris. It seems odd that the quota
file looks OK (which means that the code successfully handled
writing the limit and usage), but fails a quota check.
Actually I was setting the quota to '2000000000' which I thought
was 2GB, but I guess now was 2TB. THe system seemed to take it.
Is there some maximum for a quota in the system like 2GB no matter
what the setting is?
We had this discussion a little while ago. In the current code the
quota is set in KBs, but calculated in bytes. It's a 32 bit
variable, so the limit is 2 GB ...
Actually, it's an unsigned 32-bit value, so the limit is 4GB:

(Yes, we really do have users who are using more than 4GB of space.)
The limit is still 32-bit signed. It needs to remain unsigned because
-1 is used to disable the quota. But because the limit is set in KB,
the limit is actually 2TB. All the patch does is use 64-bit for the
quota usage so we go beyond 4GB and track up to the limit without
overflowing.
this will be different in 2.3
Yes, Ken fixed it on 2004-08-09 in the cyrus-imapd-2_3 branch.
Ken, off the top of your head, can you think of any gotchas in
backporting your quota calculation fixes to 2.2? (I don't want to
wait until 2.3 for the fix, as this bug is currently biting us.)
I don't see any problem, as the space for the extra 4-bytes is already
carved out in cyrus.index. You can probably use 'cvsps' to create a
patchset. If you don't have it, I can make one for you.
