Description

Hello,

I got the following panic while untaring my mail archive (~250000 files in
several maildirs) on DragonFly 1.4.4. Tried that on 2 machines - one with
2.5GB of RAM, another with 3GB (both UP) and it's 100% reproducible. The
same operation on my development machine (Athlon X2 with 0.5GB of RAM and DF
1.5.2, SMP if that matters) works just fine. Thanks in advance for any help.

Softupdates related.  Why am I not surprised.
Can you generate a kernel core for the panic?  I can make you a 
leaf.dragonflybsd.org account to upload it into if need be.

does this still happen on 1.6 or -DEVEL?

Lets close this bug.  If it comes up again I'll slap some additional
limits on softupdates.
