warning/JsonRpcConnection: Error while sending JSON-RPC message for identity (satellite) [2.13.7]

petr-fischer commented 1 year ago

Describe the bug

Our master-satellite sync is breaking with this error/stacktrace (from the master icinga2.log):

Facts:

error in the log occurs on the master
'xxx-satellite.domain.cz' is the satellite
'xxx' zone is the zone for hosts and checks, that are running on the xxx-satellite.domain.cz satellite
both master and satellite are on the latest icinga 2.13.7 version
after satellite restart (systemctl reload icinga2), error disappears from the master icinga2.log for a moment, the next several synchronisations are OK, but within about an hour the error starts to reappear in the log
when this error occurs in the master log, our services from zone 'xxx' are starting to switch to the UNKNOWN (purple) state in the icinga web or they seems like stopped executing
we have also another, not yet updated satellite still on version 2.10.7, and there is no error messages for this old satellite in the master

To Reproduce

I don't know how to reproduce it. If you need our exact configuration of master, satellites and agents, we can anonymize it and send, but it's probably not necessary.

Additional context

There are similar bugs here, like #9153, but the error is different (broken pipe).

What does xxx-satellite.domain.cz log when this happens?

With the stacktrace, the error probably looks more severe than it actually is. In itself, it just says that a connection got closed. Question is why that happened and why it doesn't get reestablished properly.

petr-fischer commented 1 year ago

We are planning to upgrade to 2.14 - if the error persists on 2.14, I will send the logs.

Are there any updates regarding this issue? We also experience this issue from week to week and after icinga2 logs the error, the amount of overdue checks on the satellite grows immediately. Only a restart of the instance helps.

Since Friday, April 26., we have the same problem. We have 2 Master and 16 Checker (8 Checker Zones + Master). One master and two checker of one zone now didn't syncronise with the config-master. The other seven checker-zones are working fine.

I updated both master an the affected zone to version: r2.14.2-1. The other zones are running at r2.14.0-1, 2.13.2-1 and r2.10.5-1

I found a error in the debug.log:

What´s that: "Length specifier must not exceed 9 characters"

RincewindsHat commented 3 months ago

@Skap81 Afaik, the message stream between two Icinga2 instances is Netstring encoded and the message would suggest, that message is rejected if the length specifier exceeds 9 characters, meaning more than 1000000000 Bytes (1GiB). Not sure, how it gets that big though.
