Hi All!

I installed NetBSD1.5Y on a ultra2.
All worked fine for a while but after 2 days of ininterrupted work i got the following message on the console:

panic: malloc: out of space in kmem_map
syncing disks... done
Frame pointer is at 0x19a8ae81

Before this message the machine didn't reply to any network access effort (icmp,ssh,http...)  and from console i successfully logged myself but i got only the MOTD... and no prompt and, after that, the above message.

Any Clue?

Thanks!
