Hi,
I am encountering the semgentation fault while running 2.4Stable1 as
well. I am using BSDI4.1, no diskd, cache_digest and sibling peering.
H/W: 1GB Ram, PIII-733 CPU.

Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
Is there any misconfiguration on my part or is it a bug?
thanks and looking forward to your enlightenment:)
