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: replication Fri May 8 22:09:06 UTC 2026 replication Sat May 9 01:24:31 UTC 2026 replication Sat May 9 01:54:24 UTC 2026 replication Sat May 9 02:35:23 UTC 2026 replication Sat May 9 03:09:36 UTC 2026 replication Sat May 9 03:27:06 UTC 2026 replication Sat May 9 03:39:29 UTC 2026 replication Sat May 9 03:49:37 UTC 2026 reboot Tue May 19 20:33:56 UTC 2026 replication Sat May 23 01:19:15 UTC 2026 replication Sat May 23 01:29:48 UTC 2026 replication Sat May 23 02:09:44 UTC 2026 replication Sat May 23 02:24:53 UTC 2026 replication Sat May 23 03:14:53 UTC 2026 replication Sat May 23 03:18:07 UTC 2026 replication Sat May 23 03:29:56 UTC 2026 replication Sat May 23 03:40:12 UTC 2026 reboot Mon Jun 1 19:32:23 UTC 2026 Replication process logs show memory-related events: 2026/03/24 05:49:36.742 - #1 - 1107741/1107720 - FlexibleConsumer::takeReservation: sub-consumer is dying. m_name = RMMTargetProtocolReceiver-SiteUID(0x75580fcec4e0b10a) id = 1158464514237202433 2026/03/24 05:49:36.742 - #1 - 1107741/1107720 - FlexibleConsumer::takeReservation: sub-consumer is dying. m_name = RMMTargetProtocolReceiver-SiteUID(0x75580fcec4e0b10a) id = 1158464514237202433...2026/03/24 05:49:36.791 - #1 - 1107741/1107720 - BlockBitPtrData: checkAllocationValidity, havent been able to allocate memory 2026/03/24 05:49:36.791 - #1 - 1107856/1107720 - Receiver: got compressed message for a closed task (sessionID=1968315039,replicationLinkID=(kVolSlot=814493564,srcCopyID=GlobalCopy(SiteUID(0x75580fcec4e0b10a) 0) ,destCopyID=GlobalCopy(SiteUID(0x5fd37ad021e9e8cd) 0) )) 0 2026/03/24 05:49:36.791 - #1 - 1107856/1107720 - Receiver: (sessionID=1968315039,replicationLinkID=(kVolSlot=814493564,srcCopyID=GlobalCopy(SiteUID(0x75580fcec4e0b10a) 0) ,destCopyID=GlobalCopy(SiteUID(0x5fd37ad021e9e8cd) 0) )) 0 decompressing using async decompressor to Decompress 0 mode = e_pingPong in Receiver_AO_IMPL since the task was closed a_msg.getCompressorID() = 0: a_msg.getCounter() = 0
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.
