Info

It's not entirely clear what the invalid configuration option is, but seems to be related to config server configuration. Regardless mongos shouldn't segfault. 2016-03-07T22:23:44.718+0000 E SHARDING [mongosMain] Error initializing sharding system: UnsupportedFormat: SYNC config server connection string is not allowed.

misha.tyulenev commented on Fri, 11 Mar 2016 17:18:06 +0000: Fixed: https://jira.mongodb.org/browse/SERVER-22320 Could you please confirm - that the latest master does not segfault if you're specifying the config servers in SCCC format? rui.zhang commented on Thu, 10 Mar 2016 04:20:44 +0000: Yes, with Spencer's format, it works. misha.tyulenev commented on Thu, 10 Mar 2016 02:55:22 +0000: rui.zhang please clarify are you getting this segfault by just trying to start mongos with the SYNC connection format? If you change tests to use --configdb format specified by Spencer it should work. spencer commented on Wed, 9 Mar 2016 19:51:19 +0000: Yeah, I think you need to change that to --configdb /$IPconfig1:27017,$IPconfig2:27017,$IPconfig3:27017 rui.zhang commented on Tue, 8 Mar 2016 23:31:36 +0000: let me give it a try, I am using following format for mongos mongos ... --configdb $IPconfig1:27017,$IPconfig2:27017,$IPconfig3:27017 spencer commented on Tue, 8 Mar 2016 23:28:10 +0000: Clearly the fact that this is segfaulting instead of exiting cleanly with an error message is a problem. The configuration problem triggering the segfault, however, is that you're specifying the config servers in SCCC format (listing the 3 config servers comma separated with no replset name), whereas now you need to specify the config servers with a replica set connection string (ie /,,....) rui.zhang commented on Tue, 8 Mar 2016 23:02:24 +0000: This seems not related to legacy config server, we are using CSRS in sys-perf tests.
