the 'vaadmin'-credentials.

$ nano /etc/php7/apache2/php.ini

9. Change the memory_limit from 128M to 1G

After these values have been changed the problem may be resolved.
As this workaround only changes the available memory to the SMG System, the problem may still occur.
If this is the case please consider contacting our customer support.


Secure Messaging Gateway queries the whole quarantine while browsing its contents, sometimes this
can lead to issues caused by memory-shortcomings.
If the Appliance does not have sufficient memory to execute those queries the error-message appears.
