We have an Beta App running for some user about 115 simultaneous users. When the connecntions and transactions is close to that amount of user frecuently we get this warning Could not save the audit log object after that all of the transactions or operations star to fail the only way that we solve this problem is is restarting each server. We using Windows Server 2019 OS on a virtual machine with 8 GB of RAM and 8 virtual proccesors. We have an server for each services, One to the front and others 3 for API, Identity and Database.

What can you suggest to resolve this random bug? What variable should we monitor to minimize this type of events?

    Hi,

    System.Threading.Tasks.TaskCanceledException: A task was canceled.

    It looks like the user canceled the request, not a bug.

    Run app y connect 115 user o more

    Our abo.io platform is also based on ABP and audit module and there is no problem,
