Core Router London 1 - Memory Exhaustion
Updates
The router has been rebooted.
Optimal routing has been restored.
All xDSL/FTTc/p customer connections have returned.
Free router memory has returned to an expected level.
And as a minor by product, the router firmware was updated to a level which is (according to Cisco) no lower troubled by memory leaks.
I wait to be convinced!
Apologies for the inconvenience.
Full routing tables have reloaded and all bar 6 xDSL customer connections have returned. Routing is still propagating around our core.
Apologies for the inconvenience.
The router has returned to service. Routing flaps will occur once again as the tables reload and optimum routes are restored.
Presently around 80 xDSL/SoGEA/FTTC and P customer sessions have not returned, although are popping back as I type.
A customer router reboot might be required if these do not return in the next few minutes.
Monitoring has reported free memory has dropped below a critical level.
We are about to commence a router reboot to avoid crashing into a none routing state which threatens to black hole some traffic.
A major routing update will occur across our core as providers are flushed from the routing table. This will inevitably cause poor traffic flows for a period while routes re-establish.
Apologies for the short notice, but it makes more sense to attend to this issue this evening than it potentially affect a working weekday.
