Problem Note 49607: The maximum number of database connections is exceeded when you access databases that are registered in metadata
 |  |  |  |  |
The following error message might occur when the maximum number of database connections is exceeded:
This issue occurs when you access databases that are registered in the metadata server. These orphan connections can accumulate and cause database servers to run out of available connections.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
[Error] CLI error trying to establish connection: The permitted number of client connections (510) has been exceeded
This seems to be a connection leak that occurs when you use the SQL procedure with the Metadata Library Engine.
To work around the issue, do one of the following:
- Use the native database engine instead of the Metadata Library Engine.
- For the CONNECTION= option values, use SHARED, SHAREDREAD, GLOBAL, or GLOBALREAD instead of UNIQUE. However, you might experience problems as documented in SAS Note 49604: "Too many connections are made to the Netezza database and not being dropped or reused when no longer needed."
- Clean up the orphaned processes.
