    Moved from 19.0 MR1 to 19.5 MR1 and have extreme problems with OSPF.

    We had OSPF enabled before the update and used it without problems but now after it seems crashing every 3-10 minutes.

    This behaviour occurs on 50% of our XGS116 appliances, on the other 50% it works fine.

    Will it be possible for you to provide support access ID for both types of appliances where it's working and crashing frequently?

    I will DM you for the same.

    Thanks for providing support access to the setup.

    We are able to narrow down the problem and tracking it under NC-115369 for further RCA and fix.

    There was remote network scan for /16 network getting performed over VPN, which was creating huge incomplete neighbour lookup entries. As a side effect it was causing routing demon restart.

    After stopping that scan OSPF has been stable now.
