ASF GitHub Bot updated GEODE-9443: ---------------------------------- Labels: GeodeOperationAPI pull-request-available (was: GeodeOperationAPI) > Increase kernel.pid_max in CI images > ------------------------------------ > > Key: GEODE-9443 > URL: https://issues.apache.org/jira/browse/GEODE-9443 > Project: Geode > Issue Type: Test > Components: tests > Reporter: Dale Emery > Assignee: Dale Emery > Priority: Major > Labels: GeodeOperationAPI, pull-request-available > > Certain Geode tests create a lot of threads. When these tests run in parallel > with many other tests (as they do in CI), the whole set of concurrently > running tests can overwhelm the Linux kernel's ability to assign PIDs to new > threads. When this happens, test processes, Gradle processes, and other > processes can become unable to create new threads. > The relevant system parameter is {{kernel.pid_max}}. On our CI systems, > {{pid_max}} is 98,304. > Raising {{pid_max}} to 983040 (10x the default value). A build can run 24 > concurrent instances of even our most thread-heavy tests without exceeding > this threshold. -- This message was sent by Atlassian Jira (v8.3.4#803005)
