A strange situation occurs in a service in our environment, where the memory increases by 1 GB in the case of no load. The service is developed using Tokio. The current jemallocator version is 0.3. 0, and the jemalloc version carried by the service is 5.1.0.

Version 5.1.0 has a terrible problem
jemalloc/jemalloc#1497
