This is a tracking task for all database errors and other issues related to large transactions or large writes. Large transactions causes issues because they generate lag as bad as the transaction size. To avoid that, a transaction size limit was setup, however, sometimes that limitation can cause issues- the limit should be maintained, but sometimes actions have to be split in smaller transactions or being executed in the background.
