ESXi Fails with “Corruption in dlmalloc” on HPE Server

Corruption in dlmalloc

“Corruption in dlmalloc” issue occurs because multiple esxcfg-dumppart threads attempt to free memory which has been used for configuring the dump partition. Thread A checks if there are entries to be freed and proceeds to free them, while within the same time frame, Thread B is also attempting to free the same entries.
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?
