APAR Error Description / Circumvention

-------------------------------------------------
When multiple jobs are started or running concurrently to a tape
library a MSGMCH5804 lock wait timeout may occur.

A MSGCPF4532 may occur when closing a tape file when using WORM
media.

CORRECTION FOR APAR 'SE61987' :
-------------------------------
The code has been changed to reduce the time the lock is held
and to increase the timeout value.

The MSGCPF4532 occurs because the early warning for end of media
is encountered when writing the EOF labels and the operating
system tries to overwrite the EOF labels with EOV labels. The
overwriting EOF labels with EOV labels will not be attempted
when using WORM media.

CIRCUMVENTION FOR APAR 'SE61987' :
