Identity Awareness PDP Broker disconnects with remote Subscriber constantly

[ProxyOps]

Hello,

since today we noticed that our 4 PDP Broker constantly disconnects from each other.

The output from the extendes PDP Broker log files says the following:

[9933 4059830080]@local PDP Broker[7 Jul 10:18:36] [BROKER_SUB (TD::Events)] [remote PDP Broker IP] pdp::BrokerSubscriber::reportError: called

The command "pdp br s -e" says the same:

7Jul2020 10:27:27 Subscriber failure

AND the following

7Jul2020 10:27:00 Error [56]

Can someone please explain me, what Error [56] means ?

Kind regards

Niklas

Looks like there's at least one TAC case mentioning this error and it's under investigation still.
Recommend you open one if you haven't already.

Just in case somebody is reading this, TAC and R&D found the issue a few days after I posted this.

The IA Broker crash was caused by a MUH Agent with to many users connected to the IA Broker infrastructure. A hotfix fixed the internal limitations in IA Broker code to handle much more users. PRJ-16186, IDA-3194 are the relevant fix and is also included now in R80.40 Take 119
