While testing the connection for a Postgres DB(Destination DB) endpoint getting the error on AWS DMS endpoint
Test Endpoint failed: Application-Status: 1020912, Application-Message: Cannot connect to ODBC provider Network error has occurred, Application-Detailed-Message: RetCode: SQL_ERROR SqlState: 08001 NativeError: 101 Message: [unixODBC]timeout expired
I'm able to connect to the DB directly via various DB clients using the same credentials
I have checked server logs in Azure server and see some log records as bellow:
LOG: connection received: host=xxx port=xxx pid=xxx LOG: connection
authorized: user=xxxdatabase=xxx SSL enabled (protocol=TLSv1.1,
cipher=xxx, compression=off)
LOG: could not receive data from client: An existing connection was forcibly closed by the remote host.
At: Link
It mentioned about error code WSAECONNRESET.
But from MS document Link
This code don't mean about
could not receive data from client: An existing connection was forcibly closed by the remote host.
Assume this issue related to WSAECONNRESET, so the developer need to add close command in their application to end their session?
Thanks,

I installed a MongoDB server 4.0 Enterprise Edition on a Windows Server 2012 R2 and configured kerberos authentication following the official documentation https://docs.mongodb.com/manual/tutorial/control-access-to-mongodb-windows-with-kerberos-authentication/
When I tried to connect to the MongoDB server from a client the authentication failed and I've got this error in the MongoDB server log file:
2018-07-19T16:12:00.622+0200 I ACCESS [conn4] SASL GSSAPI authentication failed for .... on $external from client .... ; BadValue: SASL(-4): no mechanism available: Unable to find a callback: 32775
Did I miss something ?

I have a problem about connection pooling on Sql Server 2008 R2 environment (OS is Windows Server 2008 R2 X64). I am periodically seeing this in Sql Server error logs:
Event ID: 18056
Description: The client was unable
to reuse a session with SPID 157,
which had been reset for connection
pooling. The failure ID is 29. This
error may have been caused by an
earlier operation failing. Check the
error logs for failed operations
immediately before this error message.
SQL 2008 and SQL 2008 R2 failure id is : RedoLoginException, 29
We have migrated to SQL Server 2008 R2 CU4, running on Windows Server 2008 R2, and the issue continues. SQL Server is having a problem communicating with one of its domain controllers when this happens.
When this happens, SQL Server Agent produces these errors:
[382] Logon to server 'DBINST01\DBINST01' failed (JobManager)
[382] Logon to server 'DBINST01\DBINST01' failed (ConnUpdateJobActivity_NextScheduledRunDate)
[298] SQLServer Error: 258, Unable to complete login process due to delay in prelogin response [SQLSTATE 08001]
[298] SQLServer Error: 258, TCP Provider: Timeout error [258]. [SQLSTATE 08001]
We checked the error logs for previous errors but the only error we can see is this error in the log files. What may cause this error and how can I investigate that?
