[j-nsp] SSG-140/NS-50 "self corrupting" flash?

[TCIS List Acct]

Hi all,

We've had a pair of SSG-140s as well as a few NS-50's seem to "self corrupt"
their flash/boot image over the last 12 months. These units are ones that were
in production previously, then were turned off for periods ranging from a week
to a few months. Upon powering them back on, they refuse to boot and require
the firmware to be re-loaded via TFTP, at which time they work fine again.
We've seen a few KB articles on flash corruption with SSG-550Ms, and have opened
up a JTAC case (which has gone nowhere).

Has anyone else seen this behavior from Juniper/Netscreen firewalls?

Hi Mike,

I haven't seen this issue before. I mostly look after a bunch of SSG5s, but I do have an SSG140 in production that was probably switched off for 3-4months before being used, no issues with it.

I did have an issue with a really old Netscreen 100 where the flash sort of died. It wouldn't let upgrade the OS to a newer version, maybe the larger image ran into some bad flash or something.

I take it you're talking about ScreenOS and not the boot loader itself? I would make sure the boot loader is up to date.

Michael.
