[Bug]: obproxy 4.3.2.0 OB_HASH_BUCKET_CONF_CONTAINER 内存泄漏 #57
Description
Describe the bug
线上obproxy内存占用一直异常增加，长时间后出现内存分配失败报错 （最大内存配置为2G）
通过show proxymemory 命令采集各个模块内存使用情况，发现OB_HASH_BUCKET_CONF_CONTAINER 模块内存占用一直缓慢增加，怀疑存在leak
如图所示：
配置 ALTER PROXYCONFIG SET mem_leak_check_mod_name='OB_HASH_BUCKET_CONF_CONTAINER';后，发现主要有以下两条trace在增加：
