   Priority:  high         |   Milestone:  2.2

---------------------------+------------------------------------------------
 Due to mutex behaviour within the !MapGuide server process, any create or
 update operation performed on a feature source may lock up the server
 process if a connection is simultaneously opened to another feature source
 in the connection pool.  Pooled connections typically include "database"
 connections like ODBC, SQL Server, and Oracle.

 Here are some cases where this may occur:

  * An author creates a new feature source on a live site with database
 connections while it is under load.
  * One user performs a buffer or measure operation while another user pans
 a map which uses a "database" connection.
