[Sam Smith]

Many thanks for this. I amended to give the container 4GB and that worked.

Kind regards,

When ClamD reloads with updated databases, the default behavior is for it to load in the new one and then unload the old one so scans can continue during the loading process.  You can also change this to disable concurrent database reloads in the clamd.conf file so it doesn't use twice as much RAM as normal during the reload.  However it will have a gap where all scans are blocked during the reload.
