Hi Scott, This may be completely unrelated, but I just went from 5.2-RELEASE to 5.2.1-RC2. After a while started seeing lots of these on the console: aac0: command 0xXXXXXX timeout after 8597 seconds and, less often: swap_pager: indefinite wait buffer: device: aacd0s1e , blkno: 2, size: 4096 I managed to observe the system in top the second time this happened. One after another, each process freezes forever in getblk. Kind of scary to watch :-). With 5.2-RELEASE, I was seeing the blocked processes, but I don't recall seeing all of that console output before. I haven't actually seen experienced any problems with 5.2-RELEASE for a while, I just have to avoid long-running find(1) processes. (E.g. put daily_status_security_enable="NO" in periodic.conf). - -- Lachlan O'Dea Computer Associates Senior Software Engineer tel: +61 3 8416 5627 fax: +61 3 8416 5810 mobile: +61 412 390 650 odela01@ca.com Relax and enjoy your shoes! -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (Darwin) iD8DBQFAMqu7oBZahcUBONoRAjwEAJ9lgMapehhkWm31HW+F0UjS9yXTKQCeJ55i y7ovo0uuLjuzqQk39Aaf6kw= =gGgc -----END PGP SIGNATURE-----
