The DDS host server has detected that an important component of the server address space has encountered a permanent error. In this case, the component that accepts incoming session requests via UNIX domain sockets (for example, PM of OS/390® APPC clients) has abnormally terminated.
The component is restarted. After 5 unsuccessful requests. the component is deactivated.
Make sure that all required prerequisites for the component are active and operational (mainly z/OS UNIX System Services).
/tmp/gpmserve/pmos390
is
free and can be used by the DDS server.If more than one instance of the DDS host server is started, this message will appear for all instances but the first one, because the UNIX socket pathname cannot be shared by different servers. In this case, always the first server will handle incoming UNIX session requests.
This message might be caused by using the old OS/2 version of PM of OS/390 which is not supported anymore. Please, insure that only the Java™ Edition of RMF™ PM will be used.
