    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:

    Check with

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

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

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

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

    Could this be a shortage of the numfile UBC parameter?
