we are currently observing an increased amount of connection timeouts on all our outbound connections to other wM components and partnersystems as well as our internal database hosts after we have updated our OS from Solaris SPARC 11.3 to 11.4.
wM version is 9.12, but not yet with latest Fixes applied.
As we have a lot of maintenance tasks to accomplish currently (Updating OS, Updating Database from Oracle 12c to 19c, …) this will take some time until we might be able to appyl the latest fixes to these environments.
For the case that SAP systems are involved in communications they note an temporary outage while testing the connections to the Program-IDs bound to our SAP listeners.
Any ideas what is causing these timeouts now, which we did not observe before performing the OS Update from Solaris 11.3 to 11.4?
Please note that we have moved the LDOMs from one physical box to another during this process to allow patching of the global box as well.
