The information in this article applies to: - Microsoft SQL Server version 4.2 for OS/2 BUG# OS/2: 1888 (4.2)

SYMPTOMS
When attempting to issue RPCs to a remote server, the RPC attempt fails with error 7205:

Can't open a connection to site '%.*s'. See the error log file in  the SQL Server boot directory. The error log file will contain the error: nconnect: no site i/o buffers are available This error will occur despite the number of requested site handlers (connections to remote SQL Servers) being less than the configured number of remote sites.

WORKAROUND
Increasing the configured number of site handlers on the local server will increase the pool of available site handlers, delaying or preventing an occurrence of a 7205 error. If the local server is cycled, the site handlers are re-initialized. This may be used to re-enable the local server to issue RPC requests.

This problem does not occur when issuing RPCs from SQL Server for Windows NT.

STATUS
Microsoft has confirmed this to be a problem in SQL Server for OS/2 version 4.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
If site handlers in use by the local server are abnormally terminated, SQL Server for OS/2 can fail to free the site handler resource for use in subsequent RPC attempts.
