We are using RDQM HA IBM MQ on Google Cloud with RHEL 8.9 and MQ v9.3.
Kmod version is 9.1.20_4.18.0_513.5.1-1.x86_64
Added parameter net.ipv4.tcp_keepalive_time=1500 in sysctl.conf
Primary node and 2 secondary nodes are in 3 different DCs. We are observing QM is getting restarted only at one specific node at regular interval but when running on other two nodes restart issue does not persists.Could you please help me out what is missing? PS: On advise on IBM PMR that has been raised we have defined net.ipv4.tcp_keepalive_time in sysctl.conf, its working for another RDQM HA setup but not working for this one.
Defined net.ipv4.tcp_keepalive_time=1500 in sysctl.conf as advised by IBM Team, but restart issue still persists.
