Hi,
I observe this issue to a very small QuickBuild 10.0.3 server (test) Is the fix have been correctly integrated into QuickBuild 10.+ versions ? I note this other issue |

| The fix was included in 10.0.3. But normally for QB server ulimit should be increased, as it can open a lot of handles considering it needs to talk to build agents and orchestrate each build job |

Ok, thanks for your response.
We have another exception that may cause this one finally. 2020-08-11 16:48:26,209 [MeasurementPollingTask] ERROR oshi.software.os.linux.LinuxFileSystem - Failed to get file counts from statvfs. {} java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.Native Need to investigate further, but we may miss some permissions, may be with Java temp dir. To stay on the initial topic, do you have a suggested ulimit number for a QuickBuild server? |
| Comment by Robin Shen [ 12/Aug/20 09:48 PM ] |
| It highly depends on your build agent number and build request volume. For a medium sized installation, I suggest to increase it to 100000 at least. |
