MySQL router on server with tomcat memory leak

Memory is slowly used by mysql router. I am running mysql router version 8.0.20 (I found there was a memory leak on mysql router 2.1.2 but mysql router 8.x is newer) I have a 3 node single-primary cluster on MySQL 5.7.30 with 13 application servers pointing to it from localhost and 1 server dedicated to mysql-router to developers. Each application server has its own mysql router locally configured as well as a tomcat server. There are about 14 mysql routers pointed at this cluster. All mysql routers are configured the same. mysqlrouter.conf [DEFAULT] user=mysqlrouter logging_folder=/var/log/mysqlrouter runtime_folder=/etc/mysqlrouter/run data_folder=/etc/mysqlrouter/data keyring_path=/etc/mysqlrouter/data/keyring master_key_path=/etc/mysqlrouter/mysqlrouter.key connect_timeout=15 read_timeout=30 dynamic_state=/etc/mysqlrouter/data/state.json [logger] level = INFO [metadata_cache:prod1] cluster_type=gr router_id=5 user=mysql_router5_qgi8an1mm3s9 metadata_cluster=prod1 ttl=0.5 use_gr_notifications=0 [routing:prod1_rw] bind_address=0.0.0.0 bind_port=6446 destinations=metadata-cache://prod1/?role=PRIMARY routing_strategy=first-available protocol=classic [routing:prod1_ro] bind_address=0.0.0.0 bind_port=6447 destinations=metadata-cache://prod1/?role=SECONDARY routing_strategy=round-robin-with-fallback protocol=classic [routing:prod1_x_rw] bind_address=0.0.0.0 bind_port=64460 destinations=metadata-cache://prod1/?role=PRIMARY routing_strategy=first-available protocol=x [routing:prod1_x_ro] bind_address=0.0.0.0 bind_port=64470 destinations=metadata-cache://prod1/?role=SECONDARY routing_strategy=round-robin-with-fallback protocol=x The memory allocated to mysql router on these 13 production servers continues to grow until it crashes the server. Currently one is using 3gb of ram. If I restart the server it frees up the memory. It seems to randomly go through these 13 and start flaring up. The one dedicated to developers, only running mysql router has not had an issue. On average the mysql router grows in memory usage by 1gb a week. About every three weeks I need to restart mysql router on these servers so that the tomcat server does not crash.
