Opened: Mar 19, 2024

Severity: 4-Minor

Symptoms

A problem is noticed when previous connections to the pool member exist and a new pool member is added with the same IP address and port. Due to this, the pool member (same IP and port) has no connections associated with it. If new connections are made to the new pool member, the stats will be non-zero

Impact

But the reason you are seeing empty stats is that the new pool member (same IP and port) has no connections associated with it. When new connections are made to the new pool member, the stats will be non-zero

Conditions

Pool members with long-lived connections are deleted after re-creating the pool member. Now the new pool member does not have any connections, so its stats will be zero until a new connection is made

Workaround

If you do not want to lose the stats, it is recommended to avoid deleting pool members with outstanding connection(s) and consider disabling them instead.
