REST timeout issue


I'm using external REST API for my app and timeout settings is set as default.(blank = 100 seconds)

When I was doing performance test on jMeter, the API shows timeout error at low probability.(like once every 100 times)

Message: "The request was aborted: The operation has timed out."

I firstly thought it's simply timeout error as it says, but the time elapsed for the API was 4000 ms(according to Integrations Log) although the threshold is set 100 seconds.
I could not find the similar case on the past discussions.
Is it because of load testing or some other reasons?

are you sure that the timeout is on the service itself? it could be a database timeout as well, e.g. when you update a entityrecord and that entityrecord is being locked because of a seconds jmeter session changing the same record.
