Azure Functions v3 deadlock issue

Hi all, we have experienced some days ago that 2 environments where we are playing with functions v3 (3.3.1) are not working properly.

Some async actions that took 15-20 mins, they are not finishing now or taking hours. We have checked inside kudu in the eventlog.xml and we have found errors related with this

One error:*"Microsoft.AspNetCore.Server.Kestrel EventId: 22 Heartbeat took longer than "00:00:01" at "03/15/2022 10:10:56 +00:00". This could be caused by thread pool starvation."

Second error: "Application: w3wp.exe CoreCLR Version: 4.700.21.35901 .NET Core Version: 3.1.18 Description: The application requested process termination through System.Environment.FailFast(string message). Message: The operation 'ListBlobs' with id 'xxxxxxxxxx' did not complete in '00:02:00'. Hit maximum number (5) of timeouts. Terminating the process to mitigate potential deadlock. Stack: at System.Environment.FailFast(System.String) at DurableTask.AzureStorage.TimeoutHandler+<>c.<.cctor>b__5_0(System.String) at DurableTask.AzureStorage.TimeoutHandler+\
