1) Message boards : Problems and Help : Stderr output (Message 90692)
Posted 1804 days ago by John Burroughs
Hi,


When I look at the workunits completed by Genefer 32768 v3.09 (cpuGFN15), I'm seeing these error messages. I have hyperthreadng disabled and I don't have my CPU overclocked. Am I doing something wrong?

My CPU: GenuineIntel
Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz [Family 6 Model 63 Stepping 2]

Stderr output
<core_client_version>7.6.9</core_client_version>
