We are using wiremock standalone jar, we have placed 3 mappings .
We are continuously hitting stubed api to get mock response, its working but the heap memory is not shrinking its continuously increasing

12/19/2023, 6:00 PMHi Raghu, it sounds like your request journal is growing unbounded. You either need to disable it or limit its size at startup.

Tom
12/19/2023, 6:08 PMOK, so setting this to true would be one solution

12/19/2023, 6:09 PMI’d suggest limiting rather than disabling unless you’re planning to run load tests.
You can do this via the CLI with something like:
Copy code
--max-request-journal-entries 1000Tom
12/19/2023, 6:09 PMAll the CLI parameters are documented here: https://wiremock.org/docs/standalone/java-jar/

Any property we need to set to perform GC , We See that GC is not performing we are running latest wiremock image in our kubernetes cluster

Tom
12/21/2023, 6:43 PMUnless you’re running a very unusual JVM setup there’s nothing you need to do for GC to happen.
What’s the visible symptom you’re seeing that makes you think this isn’t happening?

12/22/2023, 11:07 AMheap memory is continiously increasing and its not comming down even though application is sitting idle
t
Tom
12/22/2023, 11:15 AMThis is happening when there's no traffic?

12/22/2023, 12:07 PMDo you have health checks hit WireMock regularly?
r
raghu babu parmala
12/22/2023, 12:16 PMno
t
Tom
12/22/2023, 12:19 PMCould there be anything else hitting it in the background?
You could check this via the /__admin/requests endpoint
Tom
12/22/2023, 12:20 PMI ask because it sounds like you still have an unbounded request journal, so any requests being made will gradually fill up the heap
r
raghu babu parmala
12/22/2023, 12:44 PMI set it request journal value has 100
t
Tom
12/22/2023, 12:46 PMIt sounds like that hasn't applied correctly for some reason. But I can really only speculate without more information about how you're deploying and running WireMock
