Just history repeating itself... ;) https://www.cisco.com/c/en/us/support/docs/field-notices/200/fn25994.html https://www.networkworld.com/article/3122864/cisco-says-router-bug-could-be-... As the process size in fabrication gets smaller and smaller, it takes less and less energy hitting a device to cause spurious events like these. "smaller, faster, cheaper" does come with a few trade-offs. ^_^;; Matt On Mon, May 4, 2020, 08:32 Javier Gutierrez Guerra <GuerraJ@westmancom.com> wrote:

Agreed. However in this case it was not a single-event upset (or multi-event upset) but timing problem, fixable with new software on the memory controller. Single-event upsets should be benign with ECC memories. -- ++ytti
