Severity: 3-Major

Symptoms

While creating a new tenant, an error occurs: "Failure for data/f5-tenants:tenants API. The server or an underlying service is unreachable." The network-manager service seems to hang, or it might be in a restart loop. In confd, the 'show system mac-allocation state' command indicates that no MAC addresses have been allocated. $ show system mac-allocation state system mac-allocation state free-single-macs 16 system mac-allocation state allocated-single-macs 0 system mac-allocation state free-large-blocks 2 system mac-allocation state allocated-large-blocks 0 system mac-allocation state free-medium-blocks 0 system mac-allocation state allocated-medium-blocks 0 system mac-allocation state free-small-blocks 0 system mac-allocation state allocated-small-blocks 0 system mac-allocation state total-free-mac-count 80 system mac-allocation state total-allocated-mac-count 0 <--- system mac-allocation state total-mac-count 80

Impact

Tenants cannot be created.

Conditions

This can occur with combinations of tenants using MAC blocks greater the size 1. The specific combinations are somewhat unpredictable.

Workaround

None

Fix Information

The code will be updated to prevent the hang condition.
