> Web server - latest version of Tier 1 Horde components (Horde, IMP, > Turba, Ingo, Mnemo, Nag) > > Red Hat Enterprise Linux 3 with latest errata > > > > Mail server - Cyrus IMAP 2.1.18, using IMAP with TLS (although > problem occurs with plaintext as well) > > > > After using IMP for awhile, message indexes start to behave > erraticly. There are two types of problems: > > > > 1) "Requested message not found" when clicking on a message > > 2) Clicking on a folder or a link to a previous set of messages > takes you to the wrong folder > > > > Situation #1 seems to be exacerbated when you are reading messages > and when new mail arrives, although it is not limited to this > situation. A fairly reproducible situation (although not always) is > to do the following: > > > > 1) Login to Horde/IMP (we are using LDAP authentication, and our IMAP > server uses saslauthd with passthrough to the same LDAP directory > server) > > 2) Read a message in your INBOX > > 3) Do a search for messages that returns a few pages of results. > > 4) Return to the INBOX and choose a message > > 5) "Requested message not found" is returned and you're dropped back > into the search results page, instead of the INBOX page. > > > > Today, I'm not seeing the "Requested message not found" message as > much but I am getting dropped into the wrong folder when switching > between folders, on a somewhat frequent basis. > > > > While POP access is available to our mail server, there is no POP > activity on my account. > > > > I have done packet captures for non-TLS IMAP connections as well. > When the "Requested message not found" message is kicked up by IMP, > there is zero IMAP connection traffic, so its not as if the IMAP > server is returning an error. > > > > Perhaps totally unrelated but worth noting is that the occurrence of > the wrong folder being returned is worsened when using an IMAP proxy > running on the web server. I am not currently using that setup in > production, for that reason, but I can do tests on a test site if > needed. > > > > I am using Thread mode, but I see the "Requested message not found" > error in other sorting modes as well.
