After upgrading the PAMSC endpoint to CP5 (18.104.22.168), any server with an NFSv4 mount is now experiencing frequent system hangs which require a reboot.
PAM Server Control 14.1 CP5
The system hangs are caused due to deadlocks between seosd and the request-key & nfsidmap processes.
The code will be fixed in PAMSC 14.1 CP6.
When the CP6 endpoint is published, it can be downloaded from the Broadcom Support page below.
