CMTS uBR7246VXR (NPE-G2) crashinfo

[Dzano]

Hello, 

Could, please, anyone help with some advice?

At irregular intervals, all modems in the network crash. At a given time, the CMTS generates a crashinfo file (in the attachment). At a given time, an error is written in the crashinfo file: JIB3 US FATAL Interrupt detected fauna sbuf fatal double bit ecc err. What can cause this problem? Does anyone have experience with this kind of issue?

Thanx to everyone

Have you got another card you try to see if you get the same condition ?
