Scott, just for some simulated testing I installed Cyrus 2.3 on a test
box and loaded up a mailbox to over 10GB (hundreds of thousands of tiny
messages). The mailbox was still responsive, however the squat process
would take a long time to run and would lock the mailbox for long
periods while it did so. This is on old hardware (PentiumIII with a 15GB
IDE drive), but new software (Fedora Core 5, Cyrus 2.3, Postfix 2.2 or
2.3, JFS). YMMV.

Okay, I would like to hear specifically from Ken on this one...
I asked the question myself and go an answer suggesting the limit is
not 2GB,
but 2TB. I saw a posting from Ken earlier on suggesting something
similar.
In a nutshell, it looks like we can set quotas to any size (even
larger than
4GB) because the quote limit is defined in Kilobytes and note bytes.
However,
the real problem is the tracking of the actual space used by the
user, which
is done in bytes... so, even though you can set the quota larger, the
2GB
limit still gets hit because the actual usage counter overflows. Is
this how
it really is, or am I barking up the wrong tree?
There also seem to be some third-party patches out there (Simon, etc)
that
implement a "large quota patch", which gets around this problem. It
looks
like it is actually a 64-bit quota patch, which allows Cyrus to track
how
much disk space is used to greater than 4GB. Again, am I
interpreting this
correctly?
So, to wrap up this discussion once and for all:
What is the actual quota limitation for Cyrus 2.2 and for Cyrus 2.3?
(are they different? did the third party patches make it into
the 2.3 versions of Cyrus?)
Does the large quota patch require a 64-bit machine/os in order to
permit
quotas larger than 2GB?
Thanks,
Scott

Perhaps I didn't describe the max quota limit problem good enough:
When your system is affected by this problem and you set a quota
greater
than 2 GB, it results in running mad. In this case it will report
over
quota way before 2GB. Setting quota back to 2GB (or some bytes
below),
the user will be able to use this 2GB w/o problems again.
So your symptoms point exactly to this problem.
In this case, the only way to have more space as 2GB is to remove
quota
like it has been suggested here already.
----
are there any versions of cyrus 2.2.x that are fixed to allow quota's
over 2Gb or is that fix only available for 2.3.x ?
I have large quota patches in my 2.2.12 rpms which seem to work fine.
