In very rare scenarios, blade software components may be unable to communicate with the database on the system controller. LACP and STP daemons hang at startup, and it could cause other issues in a partition.


The LACP, LLDP, and STP daemons may be indefinitely unusable. It is suspected there could be other impacts depending on which blade software component is affected, though no other issue has been observed.


The issue can occur when both system controllers are rebooted at once.


1. Reboot the affected blade. 2. Disable then re-enable the affected partition.

Fix Information

The affected blade software component can now detect the connection issue and will re-establish the connection to the system controller's database.
