Errors in domain's Apache error log on Plesk server: AH01068: Got bogus version or Error dispatching request

Applicable to:

  • Plesk 12.5 for Linux
  • Plesk Onyx for Linux

Symptoms

Apache version is 2.4.15 or older.

The following error messages appear on Plesk server on the Logs page at Plesk > Domains > example.com or in domain's error log file /var/www/vhosts/system/example.com/logs/error_log:

CONFIG_TEXT: AH01068: Got bogus version 111, referer:
(22)Invalid argument: AH01075: Error dispatching request to :, referer:

Cause

This is an Apache bug 49671, which has been fixed in Apache version 2.4.16.The fix from the Apache only changes the error message from "Got bogus version {} \\ Error dispatching request" to "The client aborted the connection" so message will be more descriptive.

Resolution

Note: Apache 2.4.16 is unavailable via CentOS/RHEL 7.x default repositories. 

These error messages can be safely ignored - there are no consequences for the website.

To get rid of these messages:

  1. Log into Plesk UI.
  2. Open the tab Domains > example.com > PHP Settings > switch PHP to FPM served by nginx :
    image

    When is this planned to be fixed? The messages are flooding my logs which is quite annoying. Thank you.

    @Vitaly: I have asked for a timeline: When will it be fixed? Just future product updates is too vague. Hopefully someone from Plesk support will answer this question. 

     

    A hint: I have noticed that the error flooding stops when disabling watchdog monitoring for the Apache service.

    Is this the same error as I get it in my PHP logs:

    "AH01068: Got bogus version 27, referer: ...."  ?

    My logfile fills with about 500k per day with these messages. If it's because of a bug on Plesk's side, it would be great if it could be resolved, otherwise I would really like to know what is causing it so I can fix it on my side.

    thanks!

    Hello rookey,

    Could you please let us know if the issue is still actual for you? In addition, Plesk supports only official repositories in regards to Apache, so, you can use Ubuntu 16.04 with Apache 2.4.18.

    @Asad Qureshi,

    The bug has been fixed in Apache 2.4.16 only. You may migrate to Ubuntu 16, where Apache is 2.4.18.
