[Serusers] Message too big

[Marc Khayat]

Hi,
I installed ser-0.9.3, and registered 2 agents. However, I'm getting
error 513 "Message too big".
The only change I did to the config file is that I enabled
authentication on registration and accounting (MySQL and Syslog).

What am I doing wrong here? What can cause it?

Thx,
Marc
