mongos throws an uncaught socket exception when it can't reach the config server

    • Type: Icon: Bug Bug
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 2.4.0
    • Affects Version/s: 1.7.6
    • Component/s: Sharding
    • None
    • Environment:
      Linux x86_64
    • Linux

      Repro steps:

      Start mongos with the --configdb parameter referring to a mongod that doesn't exist:

      Fri Jan 28 17:51:17 mongos db version v1.8.0-rc0-pre-, pdfile version 4.5 starting (--help for usage)
      Fri Jan 28 17:51:17 git version: 7fa627b35627e94c94aafe9b0275de665129acd2
      Fri Jan 28 17:51:17 sys info: Linux behackett-dt 2.6.36-gentoo-r5 #4 SMP Mon Jan 24 10:24:02 PST 2011 x86_64 BOOST_LIB_VERSION=1_42
      terminate called after throwing an instance of 'mongo::SocketException'
      what(): socket exception
      Aborted

      I can also reproduce this by passing a configdb that hasn't completely settled down yet. Logging mongos to a file you can see something like this:

      Fri Jan 28 17:41:26 mongos db version v1.8.0-rc0-pre-, pdfile version 4.5 starting (--help for usage)
