[jira] [Assigned] (TS-1035) EventProcessor::spawn_thread doesn't check that there is enough event threads and segfaults
[ https://issues.apache.org/jira/browse/TS-1035?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Brian Geffon reassigned TS-1035: Assignee: Brian Geffon (was: Leif Hedstrom) > EventProcessor::spawn_thread doesn't check that there is enough event threads > and segfaults > --- > > Key: TS-1035 > URL: https://issues.apache.org/jira/browse/TS-1035 > Project: Traffic Server > Issue Type: Bug > Components: Core >Affects Versions: 3.0.1 >Reporter: Brian Geffon >Assignee: Brian Geffon > Fix For: 3.1.3 > > Attachments: LargeNumberOfPorts.patch, UnixEventProcessor.patch > > > The easiest way to see this bug is to use several hundred ports with accept > threads turned on.
