 This was configured with four b10-auth components.

 I think the corresponding logging is:

 {{{
 2012-03-27 12:32:10.427 FATAL [b10-auth.server_common]
 SRVCOMM_EXCEPTION_ALLOC exception when allocating a socket: Error while
 reading data from cc session: End of file.
 }}}

 There were several "Error while reading data from cc session" and
 CC_READ_ERROR and a traceback in b10-cfgmgr at same time:

 {{{

 (note that some regular logging is mixed in above)
