CentOS - May 2007 - Squirrelmail Problem on CentOS 4.4

Recently, some of my accounts cannot read any email in the INBOX within 
Squirrelmail. The error....

The server couldn't find the message you requested.

Most probably your message list was out of date and the message has been 
moved away or deleted (perhaps by another program accessing the same 
mailbox).

The messages are not being moved out. In fact, I can delete one of those 
messages just fine. I can also move messages to another folder. Oddly, 
once I move a message I can open and read it.. and I can open and read 
any message in the Trash folder.

So, it seems that something has changed during an update to who knows 
what, which has borked up reading mail in Squirrelmail. It does seem 
that this is occurring so far on what would amount to root users of an 
account. In other words, the user created during a hosting installation. 
So, files are stored in /var/www/rootusername. When I add additional 
email users to an account, I put their user files in 
/var/www/homes/rootuser/additionalusername.

Has anybody else experienced this? I'm a bit lost as to where to look. I 
am using Sendmail/Dovecot and have been on this server since CentOS 4 
came out. This could be any of so many things from PHP to IMAP, but 
mostly it seems to be some pathing problem.. just not sure where to begin.

The only thing I am finding in apache error logs is this:

PHP Notice:  Undefined variable:  charset_converted in 
/usr/share/squirrelmail/functions/mime.php on line 316, referer: 
http://domain_name_replaced_here_by_john.com/webmail/src/right_main.php?PG_SHOWALL=0&sort=0&startMessage=1&mailbox=saved_email

Which doesn't seem to have any affect on other users and looks like it 
refers to the folder list and not the email reader.

Thanks for any hints/help on this.

Best,
John Hinton

Maybe these accounts have too many emails in them? Check on two things:

a) squirrelmail config:
	4. General Options -> 11. Allow server side sorting=true
This speeds up query against the stored mails.

b) your php.ini has a "memory_limit = 8M" per php process. Increase it
up to 20M.

Restart Apache after these changes and see if they help.
