Take into account cpuset masks on Linux when using cpu count for sizing pools ----------------------------------------------------------------------------- Key: WFCORE-1000 URL: https://issues.jboss.org/browse/WFCORE-1000 Project: WildFly Core Issue Type: Feature Request Components: Server Reporter: Jason Greene Assignee: Jason Greene Fix For: 2.0.0.CR4 On Linux, Runtime.getRuntime().availableProcessors() always returns the host CPU count regardless of the process' cpuset affinity. This effectively means usage of cgroups (e.g. using docker) and numactl will lead to oversized thread pools. While this issue should be fixed in the JVM, we should workaround the problem by reading /proc.
