  • 1.  High memory utilisation- nimbus

    Posted 01-12-2020 10:19 AM
    Dear Team

    We have recently upgraded from 8.47 to 9.02 and applied latest fixes . We found that in one of the SNMP collector hubs memory is high at 70% and above . Memory is high with nimbus process. We have applied the 7.97 HF7 robot update and 7.97 HF6 hub

    This started after upgrading to latest fix 7.97 HF7 robot update and 7.97 HF6 hub

    Any advice on this . At this moment of time we cannot upgrade to 9.20

    Cheers

    Did you try to upgrade via the Admin console or IM?

    Try the upgrade via Admin Console. I had a case like this and that worked but the upgrade via IM did not post-upgrade.

    Those are normal messages. At least I see them all the time without them correlating to an actual issue.
