APIM server returning timeout error when calling the non-existing context continuously

[LayaniMal]

Description

The APIM server returns a timeout error when calling the non-existing context recursively during the tracing or telemetry enabled.

Steps to Reproduce

• Downloaded an APIM-4.2.0 pack
• Configure and enable the Jaeger Tracing(only need to enable tracing or telemetry) by adding the below configuration.

[apim.open_tracer]
remote_tracer.enable = true
remote_tracer.name = "jaeger"
remote_tracer.properties.hostname = "localhost"
remote_tracer.properties.port = "6831"

• Tried to call the just “/” or invalid API context.

When there is network latency the issue is reproducing and the below logs are getting printed.
