Context :

1 NT Server 4.0 (Service Pack 3, Postfix ICMP)
1 SQLServer V 11.0.3.2 (SWR 7571)
2 OpenServer 10.0.4 (EBF 7704)

All component are running on the same machine.
To communicate to the OpenServer we go through the SQL Server using an RPC.
The OpenServer have been added to the sysservers table and have been
defined with timeout to TRUE.


Problem :
At an uncertain time SQLServer is loosing connection to the two OpenServer
(EUR_SRV and EUR_SRVB).
The error message is " 7201 : unable to connect site …".


The two OpenServer process are still alive under NT and we can also " ping
" them.

Our interface file is set as the following :
;; Sybase Interfaces file

;; [<database_server_name>]
;; <link_type>=<network_driver>,<connection_info>
