What causes max-allowed packet issue in drupal 7. We have set the
max_allowed_packet size to 1024mb (1gb). Still we are facing the problem in quick intervals.
Also dblog module is not working even after enabling it from database.
Drupal version: 7.22 MySql version: 5.1.7
Using APC, Memcache and Varnish for caching.
[Edit]: We noticed that
max_allowed_packet the value gets reset to 1mb automatically.
