    The platform is great when it works, but I'm having continual reliability issues. 

    Specific issues...

    When viewing Data or Users, the system very often reports the following errors:

    "Cant read items from API server. Try again"

    "Error getting database for app: xxx"

    Access in general is also very slow.

    There are good days and bad days, but whenever I check the system status it suggests all is well. 

    We are nearing our target date for production, but user sessions are getting dropped and/or users cant login. Is this the normal service level? Or is the system going through some changes that are not reflected on the system status page?

    Additional issues:

    The Data section will often display the # items for a given type to be "0", wheras there are many records for that type. Clicking on the 0 does bring up the page of records.

    Hi Randy,

     Thank you for contacting Telerik Support. 

     Let's take a closer look for the problems you mentioned.

     [Q] The Data section will often display the # items for a given type to be "0", wheras there are many records for that type. Clicking on the 0 does bring up the page of records.

     [A] The problem is caused by a custom cloud code in beforeRead function for that Content Type. Please, double check the cloud code for that type and make sure that everything is correct. Once fixed, the expected count for that content type will be displayed in the grid. 

     [Q] "Cant read items from API server. Try again"
     
     [A] This problem is caused by the error below.

     [Q]"Error getting database for app: xxx"
     
     [A] We checked our logs and saw that you have received that exception several times in the past 24 hours. As this is the first exception from that kind that we receive, we are not quite sure what may cause it - is it some temporary problem that will not repeat or a real problem that happens all the time and have clear steps for reproduction. So, I'll log new issue in our Bug Tracking system in order to troubleshoot in details the problem and will let you know once there is a information on it.

     [Q] Access is general is also very slow.
     
     [A] Would you please specify some more details on that matter - what exactly operations are you performing, is it on API or UI level and what performance do you expect? We are in process of database migration, which should finish in a few days, however your application should be without affected performance. So, any additional information you specify on the topic will help us to analyze the problem deeper in order to ensure flawless production release for your application.

     Once again, thank you very much for listing these problems and accept our apologies for the troubles caused.

    Regards,
    Dimo
