I'm getting a kernel panic whenever I try to do a sync on the empeg. If I use any version of hijack >=244 it does this, 243 and below doesn't cause the panic. It happens when it get to the deleteing database stage...It also happens when I drop to the shell, and do a "rm /empeg/var/database"

Hardware Mk2a with an IBM 48GB HD with 17.6GB free.

Here's the output from the serial port.

I am also getting these, as evidenced by my previous thread. I am sure Mark will look into this when he has more Hijack time. I have actually gotten through a few smaller syncs, but had some large ones fail, so I guess some people get a little more luck and "your mileage may vary."

Kernel tracebacks are 100% USELESS unless you also provide the exact (unmodified) Hijack version number.

edit: Don't bother now, I'm not getting them with v263
