GetContainerItemLink and GetContainerItemInfo have been causing these errors for me in an addon I use, SmartBuff, especially after hearthing/portaling (ie. PLAYER_ENTERING_WORLD) but also at random times I've attributed to OnUpdate overload.

Basically cycling through bags and slots in a loop I've "de-compressed" the timing of these calls with a C_Timer.After as well as after the event which to-date has "fixed" this particular problem.
