In addition, I would suggest typing =3.1 in ISPF and use the compress option to free up space.

This has worked for me whenever I have encountered this message.

The B37 Abend handler is doing this. It means you have run out of space (probably a work file) in trying to extend it. It is moving the whole file over to a different volume.

The best thing is to allocate enough space in the first place without it being excessive. Then you shouldn't get this problem. Maybe the work packs are clogged up with undeleted rubbish. Do other jobs get this problem? It may require increasing the size of the DASD pool, changing file sizes, tidying up the packs or scheduling the jobs better.
