If there are many zones (e.g. 1800) a stats request for all zone stats will produce a reply message too large to be sent in one attempt. zxfrd will stall on a second attempt to send and subsequent stats requests/responses will be blocked.
Web interface appears to hang waiting for zxfrd to reply.
Config with many dns-express zones. Attempt access through the web interface (however, tmsh works).
Only view zone stats through tmsh. Otherwise, if stats are hung, perform a 'bigstart restart zxfrd'.
Bug fixed in zxfrd to continue large response processing.
