IMAPProtocol.php Email Error

[dumorian]

We are having trouble with forwarding or moving emails with large attachments. Here is the error with the domain name and some of the path changed.

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 8777169 bytes) in /var/www/example.com/public_html/egroupware/egw-pear/Net/IMAPProtocol.php on line 3352, referer: http://example.com/egroupware/index.php?menuaction=felamimail.uicompose.forward&reply_id=219861&folder=SU5CT1g%3D

This is when trying to forward a 8.6 meg email with attachments.

Also, so far, it appears that when trying to move larger emails, if the size limit is exceeded, first the email is not moved, but it is removed from for instance the Inbox which loses the email entirely. This is not good.

Looks like a PHP-related error.
Did you try to increase php.ini’s memory_limit ?
It looks like yours is 32M - modern PHPs use 128Megs by default.
If your php config is an old one, just try 64M instead of 32M.

My global php.ini settings are:

memory_limit = 256M
post_max_size = 64M
upload_max_filesize = 128M

Not knowing for sure which memory limit I was hitting, I just kept increasing the size on each of the above trying to troubleshoot. I did restart apache after each change.

Does egroupware have it’s own php settings somewhere that might override the system defaults?

I am using sendmail, dovecote and mbox format on a CentOS 5 server.

The PHP error message “Allowed memory size of 33554432 bytes exhausted” means memory_limit is 32M.
One test you can do is checking the php-info / php-configuration inside eGW (somewhere in a eGW’s admin page), and look for the memory_limit value really used.

Then try this :

• check if the php.ini file you modified is the right one (not a duplicate one)
• check if php memory_limit is not overriden :
• in apache global config (httpd.conf or other conf)
• in an .htaccess
• in a php script (in eGW, probably in a “.php” file on eGW rootdir)

My global php.ini settings are:

memory_limit = 256M
post_max_size = 64M
upload_max_filesize = 128M

Yes… When I run the PHP Information script from within eGroupware, I see ‘Local Value’ and ‘Master Value’.

These are different.

Local
memory_limit 32M
upload_max_filesize 16M

Master
memory_limit 256M
upload_max_filesize 128M

I have grepped the egroupware directory and looked all over the place and cannot find where these ‘Local’ setting are stored.

Does anybody know?

[dumorian]

Crud… I found it. I needed to grep in the web directory and found it in the .htaccess file. My bad.

The disturbing part of this problem is that there is no error message when it happens. The only hint is that the email window does not close.

The other bad thing is that the email is lost. The move out function apparently works, removing it from another email folder, but when it doesn’t make it to the other folder, it’s lost.
