Thanks for confirming gamin issues. Too bad the Fedora guys decided to
build their courier RPMs against it. I'll see what I can do on these
fronts.

I am getting very consistent problems with the imapd server hanging when
certain users attempt to access their mailboxes. I am fairly certain
that the problem is actually related to gamin/gam_server, the
file/directory change notification library used by courier. It looks
imapd is stuck in connect() or select() talking to the gam_server.
I've updated my Fedora system to the test releases of gamin
gamin-0.0.19-1.FC3
gamin-devel-0.0.19-1.FC3
in an attempt to surpass these problems, but my uptade to 0.0.17, the
latest "release" versions didn't help.
My belief in the theory that this is gamin related is strengthened by
the fact that setting IMAP_USELOCKS=0 gets rid of the hang.
Gamin is not supported yet as a replacement for FAM as Sam hasn't had a
chance to test out FC3 yet or work out the bugs. In my experience,
Courier compiled against Gamin-devel fine but ENHANCED IDLE did not work
(no folder changes were sent back to the client. Others have also
reported lockups and hanging when using Gamin with many users (my test
only involved a few test accounts). You have three options:
1. Remove gamin and gamin-devel, modify the courier.spec file and remove
fam-devel as a buildreq then rebuild courier rpm. Once the build is
complete you can reinstall gamin without fear of courier using it. Your
Courier install will no longer be capable of enhanced idle.
2. Get the latest fam SRPM from FC2 and rebuild the RPM for FC3. Remove
gamin and gamin-devel and install fam and fam-devel, recompile courier
against fam-devel and reinstall Courier RPMS.
3. If you know enough C++, figure out a patch to get gamin working :)
I'm sure Sam would appreciate not having to investigate one more issue.
