Well, to be clear, caching is turned off on my installation.
Everything is on the same box, so caching wouldn't serve any real
purpose for me, so its off.
Now, perhaps the caching code is still at fault here. As far as I
understand IMAP, viewing a particular message should be as simple as
saying "IMAP server, give me message #xxxxx please" and it gives that
message's data. Isn't that right?
If I am correct that Roundcube is processing through the mailbox in
some other way, perhaps it is related to the caching code (that would
seem to make sense). I just turned caching on to see if that changed
the results, but it didn't. Still the same escalation of memory and
timing out.
Odd. What is more complicated here than Roundcube asking the IMAP
server for a particular message? It should be cake to get the data
for a 5K message back from the IMAP server, regardless of the size of
the box its coming from. Why on earth would the httpd process climb
to 80MB+ in order to do that?

If the caching-mechanism of Roundcube decreases the performance of
the application instead of increasing it; it might be a good idea
to improve the caching-mechanism! :) I hope to be able to spend
some time on it this weekend; any additional information on the
implementation and ideas behind Roundcube current or preferred way
of caching would be appreciated

Roundcube seems to have some difficulty dealing with large mailboxes

When this happens, the browser just sits there waiting for a reply,
and I can do a 'top' on the server and watch the apache process just
eat up memory until it finally dies.
It seems that Roundcube is digging through the mail and not
releasing
memory in some way, which becomes a problem as the mailbox size gets
large. At least that's my theory.
Does anyone else observe this? This is with Apache 1.3.34, PHP
5.1.2, MySQL 4.1.18 and Cyrus 2.2.12, running on FreeBSD 4.11p14.
Is your SMTP server on the same box? If so, turn off caching in
the config, that helped me out. For record, I have ~1100 messages
in my Roundcube folder, and switching from/to this directory seems
quick. Oh, and I"m on Freebsd 6.0 with mySQL 4.x, Apache2,
Dovecot 0.9
If that doesn't help - what does /var/log/maillog say when this is
occuring?
