Hi Abed Al-R,
These messages are indicating events about failover that happened in SRX cluster nodes, the jsrpd process handles the Chassis cluster events. When one node is rebooting, it performs a failover to the secondary node in order to avoid loss connectivity that is the high availability method used by SRX, and these logs are generated.
Please check if the notes were rebooted or crashed recently and troubleshoot the reason for that. As you mentioned, CPU is high, that could be resulting in an issue with the cluster.
If there are any core files, better to log a TAC case to have them analyzed.
Hope this helps.
Regards,
-r.
