I tried several other conditions as well including Linux,
32bit OS, non-virtual environments, and so on.
However, so far, I have not been able to reproduce this issue yet
with conditions other than the following combination:
Hypervisor: VMware vSphere Hypervisor 5.1
Allocated vCPUs: 1
Allocated Memory: more than 2GB
OS: Windows Server 2012 or 2008R2 (64bit)
Run pg_dump under high load
or run pb_dump with the Low priority using Windows Task Manager
This might be a rare case.
By the way, we have already worked around this issue by adding --inserts.
Thank you.
