Dear Members,

I've got a very interresing problem with courier-imapd on Debian etch: I upgraded the system memory from 4 to 8 GB, and after the sucessfully reboot the imap folders tree are invisible. This mean: the user login is sucessfull, but user does not show any folders in the maildir (inbox, sent-mail, trash, and all user created folders), even in their e-mail client or in Webmail (horde). Before the memory upgrade the system was working perfectly since last summer.

The courier pop3 service working perfectly.

I tried to:

- install again another version of imapd with apt-get,

- setup again configuration

But it now works well.

In the system logs, including kernel, system, mail, messages, debug, but there are not any error message. I tried to log all read/system request with rsbac logger function (Log program based array) but I did not found any interrest. I tried to set up debug logging, but there is no any error message.

My configuration is:

- Debian etch ia_64 os with kernel 2.6.23.1+rsbac1.3.5

- libc6 2.7-4

- courier-authdaemon 0.58-4

- courier-authlib 0.58-4

- courier-authlib-ldap 0.58-4

- courier-base 0.58.0-1

- courier-imap 4.3.0-1

- courier-ldap 0.53.3-5

- courier-pop 0.53.3-5

All other services working perfectly.

Any idea?

Thanks,

Thomas
