This happens if the disk pool fills and migration can't keep up.  When the
client starts a transaction with the server the server is asked to create
enough room for the data.  In the case where the diskpool is full, that
space will be in the nextstg pool usually tape.  So that client is then
waiting for media.  This happens to most of the clients at this point
resulting in the q session you are seeing.

Backuppool is not very large in your configuration.  You might try lowering
high migration to 50 and see if migration can stay ahead of newly arriving
data.
