[j-nsp] Strange crash on backup RE after 240 days?

[Phil Rosenthal]

After 240 days of uptime, the backup RE on an M20 seemed to have 
crashed on it's own:

Jan 25 03:04:58  25b-6-m20-1 /kernel: WARNING: / was not properly 
dismounted
Jan 25 03:04:58  25b-6-m20-1 savecore: Router crashed.....
Jan 25 03:04:58  25b-6-m20-1 savecore: reboot after panic: 
rnh_index_alloc: nhindex 670 could not be allocated
Jan 25 03:04:58  25b-6-m20-1 savecore: system went down at Tue Jan 25 
03:02:12 2005
Jan 25 03:04:58  25b-6-m20-1 savecore: Selective dump will be saved now

At the time window in question, no one was logged into the juniper 
(either RE).

Anyone see anything like that before?
