[SM-USERS] Blank pages / no response
Hi, Currently running CentOS5.2, with Squirrelmail 1.4.17, php 5.1.6 Our users normally check email through IMAP. We only use squirrelmail for users when they have no local mail client, or to set the out of office settings or other associated account data. We are using the postfixadmin plugin for users to be able to set out office. I have a user that when she selects Options > Out of Office, she gets a blank page. Further investigation shows I can reproduce the problem by importing the database and her mail into a dev environment Her "Compose" option also returns blank page (aha!) That deleting all of her messages causes both Compose and Out of Office to correct. Which tells me that it's either a "bad" message in there somewhere of her 3200 messages, or maybe a timing issue somewhere? Thanks for any insights you might have.

As my imap server supports threading and sort, it looks like fixing conf.cfg for $allow_thread_sort= TRUE; $allow_server_sort= TRUE; resolves the problem(s) Rick At 01:38 PM 1/14/2010, squirrelm...@corwyn.net wrote: >Hi, > >Currently running CentOS5.2, with Squirrelmail 1.4.17, php 5.1.6 Our >users normally check email through IMAP.

Enable server side sorting in SquirrelMail configuration, if your IMAP server supports it. You should not turn on server side threading. It does not improve speed and only adds other option with high I/O and memory usage. Options -> Out Of Office error should not be related to mailbox or compose and there is nothing that might trigger memory intensive usage or slow execution. Postfixadmin plugin is old and might have issues with newer SquirrelMail versions. Check your webservice and php error logs. Some SquirrelMail configs can have higher memory usage. If you think that you are hitting it, try increasing PHP memory limits, reduce number of installed plugins (if I remember correctly, gpg and get_uuencode are primary suspects) or install PHP APC extension. If you want more thorough analysis, Zend sells Zend Platform. -- Tomas -- View this message in context: http://old.nabble.com/Blank-pages---no-response-tp27166220p27167143.html Sent from the squirrelmail-users mailing list archive at Nabble.com. -- Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev - squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@lists.sourceforge.net List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users

Odd to me as well, but glad it's fixed. rick -- Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev - squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@lists.sourceforge.net List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users

Maybe you confused these two options. $allow_thread_sort = TRUE; does not improve SquirrelMail performance. It might do something only when user has threading turned on for selected mailbox and server is good at sorting messages by thread. User can't turn on threading for selected mailbox, if it is not enabled in SquirrelMail configuration. If mailbox is not threaded, this option does nothing. You can't fix problem just by turning it on in SquirrelMail configuration. User does not use it. Turning off server side sorting is not good thing, if your IMAP server supports SORT extension. Could you set error reporting to E_ALL and turn on display of PHP errors? Then switch threading off in SquirrelMail configuration and try to reproduce your problem. Blank page can be caused by fatal PHP error or memory limit. -- Tomas -- View this message in context: http://old.nabble.com/Blank-pages---no-response-tp27166220p27173152.html Sent from the squirrelmail-users mailing list archive at Nabble.com. -- Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev - squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@lists.sourceforge.net List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
