On EAM process initialization, the plugin is unable to register a thread (MPI channel) with TMM on rare occasions. A subsequent system call to end the process fails.


EAM plugin is up but the access gates are not initialized correctly.




Establish connection to OAM server. bigstart stop eam Clear config.cache from each accessgates by deleting /config/aaa/oam/<partition_name>/<aaa_oam_obj_name>/<accessgate_name>/config.cache using commandline. bigstart restart eam

Fix Information

EAM plugin initialization is fixed, now the plugin register with TMM process will not fail.
