Error description

  • Following a dynamic I/O reconfiguration, KDFDEVSU places a lock
    on the device table while it builds and new one. If a query is
    run against the device table while this is happening, KS3LDEV
    will not be able to obtain the lock but may free it anyway,
    incorrectly. This occurs because the lock-held indicator is not
     being initialized properly when KS3LDEV starts. If this happens
    KDFDEVSU will incur a U0100 ABEND when it tries to free the lock
    which has already been freed
