Issue when batch-creating multiple SDLTBs programmatically with MultiTerm 2021 SR2 (16.2.1.1044) API: System.Runtime.InteropServices.COMException (0x800A0E7D)

Victor Linnemann

Dear MultiTerm Developers

We have written a converter which transforms multilingual MFT XML file into several SDLTB containing only one language pair from the XML. In most instances it will run smothly but sometimes the program runs in an error as you can see below (log file entries).

It is not foreseeable when the error will occur. It can happen while generating any of the SDLTBs. The program then will not recover from the error and  will not generate any SDLTB until it ends. If the program is started again, it begins to create SDLTBs without an error.

My question is if you are familliar with this error type and do you have an advice how to handle it?

I can share more the code if needed.

Code:

if (!application.LocalRepository.IsConnected)
{
application.LocalRepository.Connect(string.Empty, string.Empty);
}

WriteLog("Multiterm connected.");

Termbase termbase = null;

try
{
WriteLog("Multiterm try create " + sdltbNameInternal + " with " + termXDTFile + " to " + sdltbNameFull);
termbase = application.LocalRepository.Termbases.New(sdltbNameInternal, "", termXDTFile, sdltbNameFull);
WriteLog("Multiterm " + sdltbNameInternal + " opened from " + sdltbNameFull);


XPathDocument termXML = new XPathDocument(WORK_FOLDER + lang + ".xml");
XPathNavigator termNavigator = termXML.CreateNavigator();
XPathExpression termExpression = termNavigator.Compile("count(//conceptGrp)");
string nodesCount = termNavigator.Evaluate(termExpression).ToString();


ImportDefinition importDefinition = termbase.ImportDefinitions.Add("sew import definition " + lang, "", termXDIFile);
WriteLog("Multiterm import definition loaded " + termXDIFile);

WriteLog("Multiterm start import with " + termXDTFile + " " + termXDIFile + " to " + sdltbNameFull + " (" + nodesCount + " conceptGrp)");
importDefinition.ProcessImport(MtTaskType.mtScript);

WriteLog("Multiterm import finished with " + termbase.Entries.Count + " entries imported.");

termbase.Close();


if (!File.Exists(sdltbNameFull))
{
WriteLog("ERROR: " + sdltbNameFull + " could not be created!");

continue;
}

Error in the log file:

    Now that we have migrated the code of our converter to run with the API of MultiTerm 2022 SR1 we have the very same issue with this version, too.
    Any helpfull anser is welcome.

    Hi  , and  

    What can I do to avoid the error described above? It appears randomly after generating one or more termbases. Error happens when trying to create a termbase, see code sample at line 4. The input files or amount of entries are not the reason for the issue, as the converter often creates the desired termbase if started again. 

    Kind regards

    Victor
