Hi all,

I have configured an integration node to run in multi-instance mode for high availability using MQ.
IIB 10.0.0.6
MQ 9.0

I have two servers S1 and S2
mqsilist on S1:
Integration node 'IBN1' is an active multi-instance or High Availability integration node that is running on queue manager 'QM1'.

dspmq -x on S1:
QMNAME(QM1) STATUS(Running)
INSTANCE(S1) MODE(Active)
INSTANCE(S2) MODE(Standby)

mqsilist on S2:
Integration node 'IBN1' is a multi-instance integration node running in standby mode on queue manager 'QM1'.

dspmq -x on S2:
QMNAME(QM1) STATUS(Running as standby)
INSTANCE(S1) MODE(Active)
INSTANCE(S2) MODE(Standby)

I have 2 integration servers is1 and is2 on IBN1.

And everything is working fine. Then I depoloyed one REST API on is2 and from time to time active integration node become standby and standby is still stanby. So my service can't be invoked. How to resolve problem with active node become standby and why this is happening?

QM1 is still running, even node is in standby mode on both servers.

Some help, please.
