Sounds like your problem was the el-cheapo laptop hard drive they use in 
these REs.  It needs time to do it's offline maintenance, the constant log 
chatter from the various things going on in a Unix box don't really allow 
them to do it's internal maintenance, and after a while, the HDD will fail 
to calibrate and become a brick until you leave it alone for anywhere from 
a minute to half an hour, usually 10-20 minutes.

This is a pretty well known issue, and has been discussed in various fora, 
but Juniper doesn't seem to have done anything about it.
