The patch compiles and runs just fine (against an otherwise-stock r218178) so I'll first run it with "normal" load during working hours, then I'll stress test it. I think your analysis is correct given that the problem went away when I moved WRKDIRPREFIX to a UFS partition on a different disk. That made the ports tree on the ext2fs partition basically read-only so it eliminated the potential for inode contention. On that same system I built world from scratch today, but with the same scenario (src on ext2fs, obj on UFS) at -j2 without any problems. I'll get back to you after I stress the system tonight. Thanks again for jumping on this so quickly. Doug -- Nothin' ever doesn't change, but nothin' changes much. -- OK Go Breadth of IT experience, and depth of knowledge in the DNS.
