courier imap fam/gamin problem

[xstefi]

I have got problem with slow courier imap server on my Dapper 6.06 amd64 server box
(server x64 image). I have got virtual accounts in mysql. Imap is very slow when I try to list folders or read the messages. After login I have to wait about 15 sec. to read folder with 3 messages.

Installed packages:
ii courier-authdaemon 0.47-13ubuntu5.1
ii courier-authmysql 0.47-13ubuntu5.1
ii courier-base 0.47-13ubuntu5.1
ii courier-imap 3.0.8-13ubuntu5.1
ii courier-imap-ssl 3.0.8-13ubuntu5.1
rc courier-maildrop 0.47-13ubuntu5.1
rc courier-pcp 0.47-13ubuntu5.1
ii gamin 0.1.7-2ubuntu1
ii libgamin0 0.1.7-2ubuntu1

Strace for imap session:
connect(3, {sa_family=AF_FILE, path=@/tmp/fam--}, 110) = -1 ECONNREFUSED (Connection refused)
close(3) = 0
nanosleep({0, 50000000}, NULL) = 0
socket(PF_FILE, SOCK_STREAM, 0) = 3
connect(3, {sa_family=AF_FILE, path=@/tmp/fam--}, 110) = -1 ECONNREFUSED (Connection refused)
close(3) = 0
nanosleep({0, 50000000}, NULL) = 0
socket(PF_FILE, SOCK_STREAM, 0) = 3
...
...
...

I googled that it is gamin problem but gamin is already installed and running (no matter if gamin running or not, result is the same -> tooo slow :evil: ).

Any suggestions?
