SYMPTOMS
If your Zoomit VIA version 1.1b server does not successfully retrieve transactions, you may receive Abstract Syntax Notation (ASN) decoding error messages. The Zoomserv\Data\Logs\Genlogs file looks like this:

ERR_00 99/12/02 09:00:25.079 (BER_getNextAsnToken) >>>>>>>>>> Coding/Decoding error >>>>>>>>>>

ERR_00 99/12/02 09:00:25.080 (BER_getNextAsnToken) Machine state (explicit_ flag) DB_Record 

ERR_00 99/12/02 09:00:25.081 (BER_getNextAsnToken) -> Application--CONSTRUCTED- -9, length: 97

ERR_00 99/12/02 09:00:25.082 (BER_getNextAsnToken) Error occurred prior to offset: 12031488 (0xb79600)

ERR_00 99/12/02 09:00:25.083 (BER_getNextAsnToken) Error occurred in 

ERR_00 99/12/02 09:00:25.084 (BER_getNextAsnToken) >>>>>>>>>> >>>>>>>>>>



CAUSE
This problem is caused by management agents that use deltas or transactions. In Microsoft Metadirectory Services (MMS) version 1.1b, there is a maximum of two transaction database files, Tran.db and Tran.dbx. When the Tran.db file exceeds the size limit, MMS renames the Tran.db file to Tran.dbx, and creates a new Tran.db file. The ASN decoding errors occur when the server does not successfully retrieve transactions from the Tran.dbx file.



RESOLUTION
To resolve this problem, upgrade to the current version of Microsoft Metadirectory Services.

To work around the problem, follow these steps:
 * 1) Turn off all deltas in the management agents and run a full synchronization.
 * 2) Run the VIACompact tool.
 * 3) Turn the deltas back on in the management agents.

NOTE: This workaround does not prevent recurrences of the problem.

To minimize this problem, increase the size of the MMS transaction files. To increase the file size, edit the following line in the Zoomserv\Data\Config\Db5cfg file:

db5_max_tran_file_size 64000000

The default size as shown is 64 megabytes (MB); increase the file size in 64-MB increments.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
