Error trying to open Horde. Blank page shown

[SalvadorS]

Hello,

This morning when somebody tries to open a mailbox with Horde blank page is shown. URL is webmail.xxx.com/imp/redirect.php.

I read http://kb.odin.com/en/6230 but this is not my problem:

I went to /var/log/apache2/ to see error log and found this:

How can I fix this?

 

[IgorG]

Check with

# ulimit -a | grep open

how many open files allowed on your system. By default it is 1024 on RedHat based OS. Try to increase it with

# ulimit -n 8192

And add it as fs.file-max = 8192 to /etc/sysctl.conf permanently if it help.

Hi dear IgorG
This solution is temporary. I've used this solution, but when restart the server , with the same error again and again faced the problem.
Please tell how to solve this problem constantly

 

[IgorG]

Did you add fs.file-max = 8192 to /etc/sysctl.conf ?
It should fix problem permanently.

 

[Seyed AhmadS]

hi
yes
this is my /etc/sysctl.conf

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
# net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
# net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
# kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename
# Useful for debugging multi-threaded applications
# kernel.core_uses_pid = 1

# Controls the use of TCP syncookies
net.ipv4.tcp_syncookies = 1

# Controls the maximum size of a message, in bytes
# kernel.msgmnb = 65536

# Controls the default maxmimum size of a mesage queue
# kernel.msgmax = 65536

# Controls the maximum shared segment size, in bytes
# kernel.shmmax = 4294967295

# Controls the maximum number of shared memory segments, in pages
# kernel.shmall = 268435456


#added by ahmad haeri
fs.file-max = 8192

after re booting the server i run

ulimit -a | grep open

and the result is

open files (-n) 1024

Hi Dear IgorG,
is there any solution or answer?

 

[IgorG]

It is not Plesk but common Linux related question. Try to google how to set ulimit permanently on Linux.

Hi IgorG I've a similar issue with Horde.At login a blank page is shown and I must reload page for displaying items.Also logs look like this :

PHP Deprecated: Assigning the return value of new by reference is deprecated in /usr/share/psa-horde/lib/Horde/Notification.php
PHP Deprecated: Assigning the return value of new by reference is deprecated in /usr/share/psa-horde/lib/Horde/Perms.php
PHP Deprecated: Assigning the return value of new by reference is deprecated in /usr/share/psa-horde/lib/Horde/Auth.php

Any suggestion?Thanks.

Could this be a shortage of the numfile UBC parameter?
