Hm, that's interesting. Can you get a stack trace from that process? https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend > I am running PostgreSQL version 9.3 on Ubuntu 14.04 with 128GB of > memory, 800GB PCIe SSD for Database files, 1TB SATA SSD for WAL, 512GB > SATA SSD for system files. 9.3.what exactly? (You do know that 9.3.x is out of support, so even if this investigation reveals a bug, we're not going to fix it in 9.3.x. I'm willing to look anyway on the chance that there's a bug that also affects later versions.) regards, tom lane
