Friday night we observed several Brocade MLXe linecards rebooting (several locations, i.e. Amsterdam, Frankfurt, Geneva), which caused network instability due to flapping iBGP etc.
As of now we know that iWay and nine.ch suffered from similar issues in the same time window, and we believe that they use also Brocade MLXe.
Tonight around 4 a.m. symptoms occurred again, on a lesser degree. nine.ch reports it too.
For reference the tickets: http://www.init7.net/de/status/?ticket=10348 https://status.nine.ch/en/messages/544 https://www.iway.ch/iway/status/
Did anyone else observed similar symptoms?
Since these routers operate in various locations and ASNs but are the same make/model I suppose it's a software security issue. Can malicious packets force a linecard reboot?
