Our servers have been upgraded from RHEL 7.9 to RHEL 9. The CA-APM configuration seems to be broken now and causes problems on two areas:
Problem: MQ-Reply-Communication is broken as CA-APM seems to grab messages before putting it to the queue and changes the payload
The Startup time of the application server nearly doubled
Problem: with the upgrade from RHEL 7.9 to RHEL 9 the MQ-communication between our servers is broken.
Likely Cause: on RHEL 9 CA-APM grabs the reply-message for statistics and modifies the payload. The reply message cannot be parsed by the receiving system.
Only in APM 24.4.2 and later does APMIA support RHEL 9 .
