The client's CA Deliver RMOSTC Task abended with S878.
Leaving buffers allocated eventually will fill up storage and cause 80A, 878, and 40D abends.
The abends occurred after roughly 80,000 jobs are submitted by the RMOSTC task.
The buffers are in below-the-line storage and will use up around 8 MB of storage, which is enough to cause the abends.
