• Trustwave MailMarshal (SEG)
• Trustwave ECM/MailMarshal Exchange 7.X

Symptoms:

Event ID: 3502
Type: Error
Source: MMController (MailMarshal SMTP) or MEXController (MailMarshal Exchange)
Description: Transaction log file error

Causes:

The MailMarshal Controller service was unable to create a DBLOG file.

The error can be a result of the file being removed manually or by another process outside of MailMarshal's control.

The error can also result from the MailMarshal Controller service being unable to to create or rename files in the DBLog folder.

The error indicates that the MMController was unable to create a temporary database log datafile, or was unable to rename an existing temporary file.

Background

The MailMarshal Controller service, running on a MailMarshal email processing node, uses files to hold information that will later be sent to the Array Manager and written to the MailMarshal logging database. These database logging files are located in a folder "DBLog", within MailMarshal's "Logging" folder.

The MailMarshal Controller service writes the logging data to a temporary file. Periodically a new temporary file is started, and the previous file is renamed. 

As an example, the temporary file used for the database logging might be named

~SVR2003MM.455cf89f0001.dblog

Once the MailMarshal Controller service finishes building the needed SQL logging data, this file would be renamed to:

SVR2003MM.455cf89f0001.dblog

Resolution:

• Verify that virus scanners and archiving applications are not attempting to access the files.
• Verify that the MailMarshal Controller has sufficient permissions over this folder.
