This bug used to be a part of #17062, but it's actually a separate problem, so I am filing a new ticket.

Grafana link (perf1 network): https://preproduction.grafana.hedera-ops.com/d/any-stat-prom/any-stat-prometheus?from=2025-01-30T06:08:29.000Z&to=2025-02-01T03:57:31.000Z&timezone=utc&var-Datasource=grafanacloud-prom&var-network=performance&var-name1=app_accountsUsed&var-name2=Reconnect_endsReconnectAsReceiver_created&var-name3=platform_secC2C&var-name4=platform_ev_per_syncS&var-name5=Reconnect_endsReconnectAsReceiver_created&var-metric1_type=$__all&var-metric2_type=$__all&var-metric3_type=$__all&var-metric4_type=$__all&var-metric5_type=$__all&orgId=1&var-name=app_tokenAssociationsUsed&var-metric_type=$__all

This dashboard shows app_tokenAssociationsUsed metric. My understanding this metric must be consistent (actually, equal) across all nodes, but it is clearly not. It may or may not be related to reconnects. Many of these nodes had experience a reconnect or multiple reconnects before the specified time period, but I don't know if this is the source of the problem.

I did not check other metrics. There may be other metrics than app_tokenAssociationsUsed broken the same way.
