This happens when it takes more than 20 seconds to swap out a page (http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/troubleshoot.html#INDEFINITE-WAIT-BUFFER). I had the same problem some time ago with FreeBSD 6.0 when making Backups (so the disks were busy). For me it helped to increase the timeout from 20 to 40 seconds in vm/swap_pager.c (http://fxr.watson.org/fxr/source/vm/swap_pager.c?v=FREEBSD60#L1103) -- Martin
