We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
#5806 - Error notifications may sometimes be unusually large and passing MySQL max_allowed_packet
A temporary fix was put in place a few days ago... strings in stack traces are now subject to truncation. And POST params are as well.
Also a fallback was added; if an error notification exceeds 256 kb, it will instead be dumped to disk with the path in the notification. If that fails, the notification will contain the error but truncated to 256 kb.
