Table 'db.wp_90817682_options' doesn't exist errors in log

Is anyone else getting this kind of error? I’m seeing it several times a day in the log.
[22-Dec-2015 14:11:59 UTC] WordPress database error Table ‘db.wp_90817682_options’ doesn’t exist for query SELECT option_value FROM wp_90817682_options WHERE option_name = ‘wp_90817682_user_roles’ LIMIT 1 made by wp_xmlrpc_server->serve_request, IXR_Server->IXR_Server, IXR_Server->__construct, IXR_Server->serve, IXR_Server->call, IXR_Server->multiCall, IXR_Server->call, call_user_func, Jetpack_XMLRPC_Server->json_api, WPCOM_JSON_API->serve, WPCOM_JSON_API->process_request, call_user_func_array, WPCOM_JSON_API_GET_Site_Endpoint->callback, WPCOM_JSON_API_GET_Site_Endpoint->build_current_site_response, get_site_url, switch_to_blog, WP_Roles->reinit, get_option

The user is also getting this error when attempting to edit some pages “This web page has a redirect loop ERR_TOO_MANY_REDIRECTS” I do not know if they are related. I’ve just checked the log and found the errors while investigating the redirects error.

I have no idea where to start with this. We do have multi-site but the highest site number is 3 not 90817682!!

Any suggestions welcome
