On our well-behaved and moderately loaded system, I am not seeing a problem with anything in v4.2.2.2 (AIX 4.3.3). However, on the more 'abused' systems, ones that are constantly migrating and have users on them all the time, the expiration hangs whenever there is a migration, reclamation or move data going on. Simultaneous expiration and migration wasn't a problem on the well-behaved server.
I am letting one run with a migration right now to see if it eventually resolves itself (deadlock?). Right now, it's going on 15 minutes and has locked up the other migration process. I'm not sure if backups to the disk pool are affected yet. At 30 minutes or so, I'll halt the server, restart and call the problen in. Gretchen Thiele Princeton University
