WebClient crashes when running large reports (BC14CU01 onprem)

(0) ShareShare
ReportReport
Posted on by fsqq 5

When running reports that should display large number of records, webclient freezes and after few minutes, whole webclient instance stops responding (for all users, not just the user running the report).

My observations so far:

  1. CPU usage rises of the Prod.Client.WebCoreApp.exe rises to 25% (I assume that is the maximum ?) and RAM usage grows steadily
  2. There are no errors in server's event log. Is it possible to up the logging level?
  3. So far it looks like all reports are affected when are too many records to display
  4. This issue only happens when using web client, windows client shows these reports without problems
  5. Other webclient instances connected to the same BC instance are not affected


Version: Business Cental Spring 2019 Update 14.0.32615

Did any of you encounter this issue?

    I have seen this occure when you run the Business Central server tier on virtual machines using dynamic memory allocation. So i would start by checking the memory configuration on the service tier and sql server machines.

    does this occur only on one workstation or only for one special user?

    is that report customized?

    We see this issue when run inventory to gl reconcile report.

    Looks like user get timeout message but report still running and service consumes all memory. At some point nobody can login any more and user who login before is very slow.
