-----------------------------------------------------------------
Looks like the issue is caused due below
Explaining testcase states:
# Queue A 2048MB(1 container) and Queue B 13GB(13 containers)
# 2GB (1 container) submitted to Queue A and 1GB(1 container) added to Queue B
# ExpireEvent for 2 containers for Queue B app 2 is send
# Randomly container on queue B which is waiting is not allocated. Mostly
because we have limit of ANY request that can be served.
Tried running locally with patch about 60 times its success.
