Is ParseWithClaims function make a memory leak ?
Is ParseWithClaims function make a memory leak ?
I use golang-jwt/jwt/[email protected] to parse jwt string to struct by ParseWithClaims. Our service have 1350 req/sec at peak time. So I monitoring the pods memory and visualize its by grafana see below
After that I dump the heap profiling from our services and visualize its by go tool pprof and selected the sample to inuse_space. Pls See below

My implemented code. See below
_, err := jwt.ParseWithClaims(jwt, claims, func(token *jwt.Token) (interface{}, error) {
return config.secret, nil
})
Thanks for the detailed issue. Can you please provide more details on the Keyfunc you're passing to ParseWithClaims. Is it as you have written it as a config.secret, or is there a more involved implementation?
Also, are you using custom claims and embedding those provided by this package?
Ideally, I'd like to reproduce this locally to mimic your environment as much as possible.
@mfridman Sorry for late replying from your question KeyFunc is just a simple function
_, err := jwt.ParseWithClaims(bpJWT, bpClaims, func(token *jwt.Token) (interface{}, error) {
return config.Secret, nil
})
Now, I already solve this problem. Let's me explain it. In my case I used this as internal service that will received the jwt token from other internal service so when it used it internal decided to ignore error when secret is invalid. So when I fix it by update the secret to correct secret the memory did not leak. But, I still have a question why when I ParseWithClaims and ignore the error it will got memory leak. You can reproduce by heavy call ParseWithClaims function with invalid secret you will found the heap memory leak on pprof report.

Thank you for those details. We've recently refactored the project, so I'd like to investigate the v5.0.0-rc.1 release
