[jira] [Commented] (TS-1759) encouter Sig 11 while enable cluster
[ https://issues.apache.org/jira/browse/TS-1759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13774258#comment-13774258 ]
Zhao Yongming commented on TS-1759:
-----------------------------------
most of the server session problem is introduced by the session sharing, set the share level lower, the problem should be reduced if not fixed.
set proxy.config.http.share_server_sessions to 1 or even 0, may help.
that is not a finnal solution, for the current master, most of the hidding problems are figuring out and fixed. the event or session floating is evil
