|Ticket Description:||swiEZ3 crashed in preparation for software upgrade|
Problem Description:In preparation of the planned software upgrade tomorrow, swiEZ3 apparently crashed during addition of the new software packages. Apparently due to memory exhaustion.
Traffic has been automatically re-routed to alternate paths, although there were obviously some routing issues inbetween because EZ3 remained active while in a panic state.
As of 17:20 it seems we've reached a steady state again.
The software upgrade tomorrow will take place as planned.
If you notice any problems in the meantime please let us know.
Affected:From 2017-07-26 17:00 until 17:20
Impact: no more redundancy
Service: network access
Sites: Careum, EmpaEawag, ENSI, ETH, NAZ, SWITCH, UKB, UZH
swiEZ3 is restored in a steady state. Memory consumption is also in a better state than before, so the upgrade tomorrow to a new release should be possible as planned
issued reload command on console which caused a switchover to the backup RSP and session started to come up again.
swiEZ3 started to automatically partially shut down services after running out of memory due to the preparation of the software upgrade packages.
