Issues Identified in MMCloud Bondi 1.2 Release

Known Issues and Limitations

  • When using the web CLI, the command user passwd <user> --passwd <new_password> closes the connection to OpCenter.

    Workaround: use this command from a terminal session.

  • A rapid increase in memory utilization (spike) can result in an out-of-memory (OOM) error even if WaveRider is enabled.

    The parameter mem.upperBoundDuration defines the time that memory utilization must remain in an elevated state before job migration is triggered. If the memory utilization spikes, OOM can occur before the time specified by mem.upperBoundDuration has elapsed.

  • If an AWS EC2 rebalance recommendation signal is received while a job is being migrated manually, the job might fail.
