Serious session error detected.

Hey All,

I am testing Moodle 2 but I frequently get:

Serious session error detected.

Please notify administrator, this problem is most probably caused by small value in max_allowed_packet MySQL setting.

I find it strange that MySQL has something to do with it, but well... the setting is :
max_allowed_packet 16777216

Which sounds like plenty enough (16Mb)


This happens for example always when I click 'backup' in a course.

I've got the same problem trying to activate editing mode of courses.

I'm running 2.0 preview 4 HEAD from 19.08.2010.

Looks like somebody also posted the problem in a second thread:
http://moodle.org/mod/forum/discuss.php?d=153466

Is this a real bug of the 2.0 version or a settings problem?

Help greatly appreciated.

Paul
