[whups] too many open files

[Lukas Meyer]

Dear list,

I'm trying to set up mail-filter.php for our whups ticketing system.  
I'm running into the following problems when i try to pipe a message  
as a ticket trough mail-filter.php. Sometimes the ticket appears in  
whups and sometimes there are too many open files.

Of course I could raise the max.file_size but I'm wondering why mail- 
filter.php needs to access the ldap database. I'm storing only the  
user Prefs in LDAP but of course the tickets are stored in mysql. Can  
anyone tell me what mail-filter needs to do in ldap and if I can  
disable that.

This is my error message:
# echo "test" | mail-filter.php --queue test --type test --priority  
ok --state ok
PHP Warning:  factory(/var/www/staff/horde/lib/Horde/Prefs/ldap.php):  
failed to open stream: Too many open files in /var/www/staff/horde/ 
lib/Horde/Prefs.php on line 807PHP Fatal error:  factory(): Failed  
opening required '/var/www/staff/horde/lib/Horde/Prefs/ 
ldap.php' (include_path='/var/www/staff/horde/lib:.:/pear/lib:/var/ 
www/pear/lib') in /var/www/staff/horde/lib/Horde/Prefs.php on line 807

regards,

Lukas
