Win32comm driver error 995

SQL Server has encountered 2 occurrence s of cachestore flush for the 'Object Plans' cachestore part of plan cache due to some database maintenance or reconfigure operations. SQL Server has encountered 2 occurrence s of cachestore flush for the 'SQL Plans' cachestore part of plan cache due to some database maintenance or reconfigure operations.

SQL Server has encountered 2 occurrence s of cachestore flush for the 'Bound Trees' cachestore part of plan cache due to some database maintenance or reconfigure operations.

Check this thread and see if it helps. Ensure that Auto close option is turned off for the databases. We have around 30 databases which are restored daily as a part of build verification using these backups.

I see some of the databases not the same every time in restoring state for unknown reason. The next time when the restore is executed it runs fine. When the third and the fourth database of the batch are in the process of being backed up, the NT system backup is completely processed and the memory that is to be used for creation of virtual device is freed. The OS error code can be removed by splitting the SQL database into multiple policies, which will individually backup few databases at a particular instance.

In addition to this, the second method that can be used is increasing the physical or virtual memory, which can overcome this issue. So it is better to repair corrupt SQL. Log in or register to rate. My problem is that this takes time from the measurement and degrades the performance of the program.

USB drivers are rather notorious trouble-makers. Don't expect great outcomes if you get arbitrary time-out errors. Look for a driver update instead, contact the vendor for help. I agree with Hans - you will probably want to contact your USB-serial vendor. As a developer who has worked extensively on that type of technology I can vouch that it's hard to get things to look exactly like a true serial port. When I see cases like these we add a regression test for the behavior and fix it - hopefully you can have the same luck with your vendor.

HansPassant There seems to be some agreement on meta that posting that as an answer would be a good thing to do. Add a comment. Active Oldest Votes.

The computer must be trusted for delegation and the current user account must be configured to allow delegation. The system cannot contact a domain controller to service the authentication request.

Please try again later. The smartcard certificate used for authentication has been revoked. Please contact your system administrator. There may be additional information in the event log. An untrusted certificate authority was detected While processing the smartcard certificate used for authentication. The revocation status of the smartcard certificate used for authentication could not be determined.

The smartcard certificate used for authentication was not trusted. The smartcard certificate used for authentication has expired. The Kerberos subsystem encountered an error. A service for user protocol request was made against a domain controller which does not support service for user. An attempt was made by this server to make a Kerberos constrained delegation request for a target outside of the server's realm.

This is not supported, and indicates a misconfiguration on this server's allowed to delegate to list. The revocation status of the domain controller certificate used for smartcard authentication could not be determined. There is additional information in the system event log. An untrusted certificate authority was detected while processing the domain controller certificate used for authentication.

The domain controller certificate used for smartcard logon has expired. Please contact your system administrator with the contents of your system event log.

The domain controller certificate used for smartcard logon has been revoked. A signature operation must be performed before the user can authenticate.

One or more of the parameters passed to the function was invalid. Client policy does not allow credential delegation to target server. Client policy does not allow credential delegation to target server with NLTM only authentication. The PKU2U protocol encountered an error while attempting to utilize the associated certificates.

The returned buffer is only a fragment of the message. More fragments need to be returned. Early start can be used. An error occurred while performing an operation on a cryptographic message. The cryptographic message does not contain an expected authenticated attribute. The content of the cryptographic message has already been decrypted.

The content of the cryptographic message has not been decrypted yet. The enveloped-data message does not contain the specified recipient. The cryptographic message does not contain all of the requested attributes. The streamed cryptographic message requires more data to complete the decode operation.

The certificate does not have a property that references a private key. Cannot find the certificate and private key to use for decryption. Not a cryptographic message or the cryptographic message is not formatted correctly. The signed cryptographic message does not have a signer for the specified signer index.

The revocation function was unable to check revocation for the certificate. The revocation function was unable to check revocation because the revocation server was offline. The string contains an invalid X name attribute key, oid, value or delimiter. The Put operation cannot continue. The file needs to be resized. However, there is already a signature present.

A complete signing operation must be done. The cryptographic operation failed due to a local security option setting. The called function was unable to do a usage check on the subject.

Since the server was offline, the called function was unable to complete the usage check. None of the signers of the cryptographic message or certificate trust list is trusted. An object could not be located using the object locator infrastructure with the given name. Certificate service has been suspended for a database restore operation. The certificate contains an encoded length that is potentially incompatible with older enrollment software.

The operation is denied. The user has multiple roles assigned and the certification authority is configured to enforce role separation. It can only be performed by a certificate manager that is allowed to manage certificates for the current requester. Cannot archive private key.
