obproxy扩缩容后内存使用量持续增长，业务报错obproxy无法连接

OceanBase 技术问题
#3

完整obproxy日志如下：
obproxy.zip (36.0 MB)

#4

内存扩容是通过ocp扩容的么。history_mem_size看配置还是2G

#5

odp版本是：4.3.2.0-42 上面贴的是ob版本了

#6

目前内存已经扩容，通过ocp的obproxy的参数管理扩容的，当前已经扩上去了，主要想排查下扩缩容后obproxy内存持续上涨的问题

#7

https://www.oceanbase.com/docs/common-odp-doc-cn-1000000005053696
根据这个文档提供一下内存信息结果及堆栈

#8

obproxy 内存告警 这个帖子是不是跟你这个一个问题？

#9

当时扩缩容完成后，过了一个小时，内存就已经超80%了，后续到下午就增长到100%不可用了，也打印了MEMORY LEAK CHECK

#10

那个帖子是排查当时为什么ocp没有产生内存超限的告警的吧，是同一个生产故障提出的

#11

通过上面的MEMORY LEAK CHECK打印的几个堆栈能诊断吗，生产环境开mem_leak_check_mod_name担心有业务影响的

#12

obproxy：4.3.2.0-42 开源版本的debug包从哪里可以获取

#13

官网上没有obproxy：4.3.2.0-42 对应的安装包及debug包下载的

obproxy：4.3.2.0-42 开源版本的debug包从哪里可以获取

#15

mem_leak_check_mod_name='XXX' ，将检测范围限定在具体的模块，能有效减小检测的内存和 CPU 消耗。
debug包这边找一下

#16

obproxy打印堆栈不需要debug包。
使用addrline -Cfe obproxy

#17

不装debug打印的很多是?的

将上述日志中MEMORY LEAK CHECK打印的几个堆栈解析，会是？找不到符号的吧

#19

内存不足时，会将内存分配量最大的10条地址打印到MEMORY LEAK CHECK中，解析10条地址结果如下，帮忙看看哈

show proxymemory内存信息结果是啥样的

这个是当时的结果输出

#22

OB_CONCURRENCY_OBJ_POOL 这个内存分配的标准是什么，这个1.5g是如何积累的，是有上线和自动释放没有
种缓存机制应该都有过期策略和内存不足的情况下，换出的机制才行，并且要有内存限制？能不能限制这个模块
