This might interest some members. It has been announced by Intel's latest Skylake CPU has serious bug which hangs applications with complex threading which postgresql could *potentially* fall into. I don't know if anyone has experienced this or not. "Hello All, Intel has identified an issue that potentially affects the 6th Gen Intel® Core™ family of products. This issue only occurs under certain complex workload conditions, like those that may be encountered when running applications like Prime95. In those cases, the processor may hang or cause unpredictable system behavior. Intel has identified and released a fix and is working with external business partners to get the fix deployed through BIOS." https://communities.intel.com/thread/96157?start=15&tstart=0 Good luck -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
