Fortunately I was able to solve this problem.

It seems that it was related to the error I mentioned in another message
in this thread that appeared a few seconds before the memory exhaustion
error:

----------
Invalid VObject, line 1 did not follow the icalendar/vcard
format [pid 1051 on line 143 of "/usr/share/php/Sabre/VObject/Reader.php"]
----------

Apparently the php-saber-vobject package has the
/usr/share/php/Sabre/VObject/Reader.php file.

It seems that I didn't have this Debian package installed:

----------
# aptitude search php-sabre-vobject
p   php-sabre-vobject
          - library to parse and manipulate iCalendar and vCard objects
p   php-sabre-vobject-3
          - library to parse and manipulate iCalendar and vCard objects
----------

So I try to install it by previously making a backup of the previous
version of /usr/share/php/Sabre/VObject/Reader.php:

Out of curiosity I was checking if after the installation there were
differences between both files:

----------
# diff /usr/share/php/Sabre/VObject/Reader.php
/usr/share/php/Sabre/VObject/Reader.php.bkp
87c87
<     static private function readLine(&$lines, $options = 0) {
---
>     private static function readLine(&$lines, $options = 0) {
179c179
<     static private function readParameters($parameters) {
---
>     private static function readParameters($parameters) {
----------

I'm not sure if there will be anything beyond that difference in other
files, but Sabre's error and memory exhaustion no longer occurs.


Kind regards,
Daniel
