[jira] [Comment Edited] (TS-2035) traffic server cores on startup when enabling multiple ports

["Alan M. Carroll (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-2035?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13709197#comment-13709197 ]

The root cause here is that start_HttpProxyerver() is called before api_init(). This means connections can come in before api_init(), in which case HttpClientSession::new_connection uses http_global_hooks before it is initialized.
