Users who abuse lua error_reply will generate a new error object on each error call, which can make server.errors get bigger and bigger. This will cause the server to block when calling INFO (we also return errorstats by default). To prevent the damage it can cause, when a misuse is detected, we will print a warning log and disable the errorstats to avoid adding more new errors. It can be re-enabled via CONFIG RESETSTAT. Because server.errors may be very large (it may be better now since we have the limit), config resetstat may block for a while. So in resetErrorTableStats, we will try to lazyfree server.errors. See the related discussion at the end of #8217.
