MPOS freezes when offline mode is activated

(0) ShareShare
ReportReport
Posted on by Mats K. 87

Hi all, 

We experience from time to time that our MPOS freezes, with the only fix (that we know) is to re-install the MPOS application. 

We are not able to force the error ourselves, but it seems like it happens when the MPOS briefly loose internet connection. So the MPOS is going into offline mode, and almost immediately trying to get online, but this is where it freezes. 
When this happens we are not able to look up products, we can't log of and we can't finish the transaction. 

When we are trying to connect to the database we get this error message:
"You can't connect to online mode, when a transaction is ongoing. Finish the transaction and try again."

Have anyone experienced the same problem? And what did you do to fix it?

Thanks, 

MK

    I'm glad you found actionable error information by analyzing the recommended logs, please don't forget to always look into the logs first if anything doesn't work as expected - that will often save you lots of time.

    Hi, 

    It did not help to restart the IIS when this happend again.

    We now found the error message "System.Data.SqlClient.SqlException: Could not allocate space for object 'crt.DOWNLOADSESSION'.'PK_DOWNLOADSESSION' in database 'RetailOfflineDatabase' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup". 
    So we will try to fix this, and hopefully this will solve the issue.

    Did you check MPOS logs in Windows Event Viewer for warnings/errors potentially explaining your experience?

    Hi partner,

    Did you try restarting the IIS?
