[imp] random imp mail access error

[Veiko Kukk]

Hi,

sometimes some users are unable to access their mailboxes. They log in
to horde/imp, but cant access their e-mails. When that error occurs,
something similar is in apache ssl request log.

TLSv1 DHE-RSA-AES256-SHA "GET
/horde3/login.php?url=%2Fhorde3%2Fservices%2Fmaintenance.php%3Fdomaintenance%3D1%26amp%3Bmodule%3Dimp&nosidebar=1&horde_logout_token=NEBlbMxEdXduoOipCcoAedsXCk8&app= 

HTTP/1.1" 2335

but when everything works correctly:

TLSv1 DHE-RSA-AES256-SHA "GET
/horde3/imp/mailbox.php?mailbox=INBOX&mailbox_token=GJYADByxYWG_PdIzY3oDNwlQthc&no_newmail_popup=1 

HTTP/1.1" 8863

Tested with different browsers on different windows client machines.
Any ideas?

Horde 3.3.3
IMP 4.3.3
Turba 2.3.1
Vacation 3.1
