The following error is shown when trying to export the database using PHPMyAdmin:

    Nginx 502 Bad Gateway


This behavior was caused by internal software issue with ID PPA-179. the fix is considered to be included in one of the next PA updates.


The issue has been fixed in MU 6. Please install all the updates to fix the issue.


As a workaround please perform the following steps on the management node:

  1. Set apc.enabled = 0 in the /usr/local/psa/admin/conf/php.ini configuration file.

  2. Restart sw-engine service:

    # /etc/init.d/sw-engine restart
