Having the following error on one of my 3CX installs. It's running on Windows Server 2016. The description for Event ID 0 from source PostgreSQL cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: FATAL: could not reattach to shared memory (key=000000000000018C, addr=0000000002990000): error code 487 Occasionally when I get these errors I get very erratic 3CX behavior, like a service hang and all extension need to re register before they are useable again. This error occurs for me every 1-3 days. PostgreSQL has some info in forums relating to bugs in version 9.2.4 causing this issue and it appears that is what 3CX is running on currently. Any chance that 3CX will be upgrading the binaries to a more current version? The 9.2.4 is almost 5 years old now.
