Starting at 06:00 GMT+8 on December 8th, a rollback failure due to invalid transactions on some account chains has caused all SBPs who are still on gvite-1.0.3 to produce blocks incorrectly. The problem has been solved with a newly released gvite-1.0.4(bug fix) now. All SBP nodes are required to install the fix as soon as possible, in order to avoid intermittent block producing issue.
