System: NetBSD 1.5Q NetBSD 1.5Q (SETTINGSUN) #9: Thu Jan 11 23:32:20 MET 2001
Architecture: sparc64
Machine: sparc64

With only 64 MB of memory on a sparc64 machine I could reproduceably panic
the machine by removing large, deep file trees.

I have no clue if this is sparc64 pmap using a to low NKMEMPAGES_MAX value
or a general runaway ubc/softdep problem (that's why category is kern, not
sparc64, please reassign if analyzis points at culprit ;-) )


when /usr/pkgsrc is the complete NetBSD pkgsrc tree, on ffs, with softdeps

rm -rf /usr/pkkgsrc
