RecoverPoint for VMs: RPAs in Reboot Regulation due to Replication Process Restarts

RecoverPoint Appliances on the target cluster detach from the clusters (Reboot Regulation) due to replication process restarts.

This issue occurs on RecoverPoint for Virtual Machines 6.0.3.1 or 6.0.3.1.HF1.

Production cluster shows other cluster in unknown state:

No remote communication between clusters in the system

- LAN connection between all RPAs is unknown
- States of all RPAs are unknown
- States of all splitters are unknown
- States of all devices are unknown

Many replication restarts under file /home/kos/kbox/utilities/regulate_reboot/detailed_startup_information.txt of the affected appliances:

A pointer or return address in the replication stack is overwritten with string data. This is a sign of a stack buffer overflow or use-after-free where string content overwrites control data.
