I just curious if this blocker issue was already resolved or is there any walk-around available to avoid this. Since it is identified as a blocker and had opened for more than a year, i wonder how other managed to get around it! I have similar issue encountered by Joshua and it can happen few times a day as our load is extreme high. Any help will be appreciated.

Below is what the thread is waiting for:
