“Corruption in dlmalloc” issue occurs because multiple esxcfg-dumppart threads attempt to free memory which has been used for configuring the dump partition.

Based on VMware KB2147888, this issue is resolved on ESXi 6 U3. But why issue is happening on ESXi 6 U3 or ESXi 6.5 U1 when they are installed on HPE ProLiant servers?
The Hardware Sensor Status Reported in the vSphere Web Client Do you have any HPE ProLiant Gen10 on your virtual environment? Did you upgrade their iLO firmware to 1.30? If you have the servers with upgraded iLO firmware, you may face with the below status on Hardware status tab in vSphere Web Client: VMware vSphere 6.0 VMware vSphere 6.5 VMware vSphere 6.7 Good news, HPE engineers are working on this issue and it has no impact on production. It can be safely ignored but I recommend that install the new firmware after release.
Persistent memory (PMEM) is a new technology that has the characteristics of memory but retains data through power cycles. PMEM bridges the gap between DRAM and flash storage.
HPE Serviceguard for Linux (SGLX), a high availability(HA) and disaster recovery (DR) clustering solution, increases uptime for your critical applications by protecting them from a multitude of infrastructure and application faults across physical or virtual environments over any distance. It reduces the impact of unplanned downtime with no compromise on data integrity and performance. Furthermore, it helps achieve near zero planned downtime for maintenance.
The Smart Update Tools (SUT) are a SUM extension that enables HPE OneView and servers HPE iLO Amplifier Pack to stage, schedule and apply updates automatically to reduce IT operations.
