[jira] [Resolved] (TS-1327) Crash report:
thread_alloc (this=0x1162060, t=0x0), in
HttpSM::do_http_server_open
[ https://issues.apache.org/jira/browse/TS-1327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leif Hedstrom resolved TS-1327.
-------------------------------
Resolution: Duplicate
Fix Version/s: (was: 4.2.0)
Assignee: (was: Alan M. Carroll)
I think this duplicates the generic problem with share_server_sessions=2.
Lets combine these bug reports into one, TS-1666. amc, if you have some good ideas on this problem, please assign TS-1666 to yourself.
