    (20014)Error string not specified yet: Error retrieving pid file /exlibris/sfx_ver/sfx4_1/<instance_name>/logs/apache/httpd.pid

    Resolution

    1. Login as the Unix instance user.
    2. Run the following commands:

    a. ps -ef | grep httpd | grep <instance_name> (in order to find the pid number)
    b. kill -HUP <pid_number> (in order to update the file)

     

    1. If you still encounter this error, you should restart the instance apache using these steps:

    a. server_admin_util
    b. 1 Start/Stop services
    c. 8 Instance Apache restart
