Magento – Error while sending QUERY packet on static-content:deploy

I get the following error when I use static-content:deploy -vvv.
How can I remedy this?

If it is an issue with SQL max_allowed_packet, I am on a shared server so cannot change this myself, but may be able to get my host to change this if I have a good reason.

[Exception]
