obproxy扩缩容后内存使用量持续增长，业务报错obproxy无法连接

李元锴 · 2026 年3 月 11 日 10:43

【使用环境】生产环境
【 OB or 其他组件】
obproxy
【使用版本】
集群版本详细版本号（带小版本）：obproxy ：4.2.5.1-101000092024120918
CPU架构（x86/arm）x86_64
【问题描述】清晰明确描述问题
在进行obproxy节点替换（3节点obproxy集群-> 增加3个节点->删除原有3个节点）后，obproxy内存使用量持续增长，下图是近3天的内存使用量，扩容后开始异常增长

3月7日晚上变更操作步骤如下：
21:46在当前obproxy集群上新增 10.191.205.230 、10.191.205.231两台节点，任务在21:48完成，21:51增加另一个节点10.191.205.232，任务在21:52完成
22:55删除原有集群的3个节点，任务在22：57完成
从ocp监控图上看，3月7日的23点开始obproxy的内存持续增长，到8日15点手动重启obproxy后下降，扩容了obproxy_memory_limit到6G了，目前看还在增长
obproxy扩容前后的版本一致，操作系统的版本一致，obproxy上的连接数、qps变化不大，期间无业务层的变更
【复现路径】问题出现前后相关操作
【附件及日志】
关键日志：其中ObBufAllocator模块申请了1,074,263,040 实际使用才：426,159,360 疑似泄露

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

李元锴 · 2026 年3 月 11 日 11:30

odp版本是：4.3.2.0-42 上面贴的是ob版本了

李元锴 · 2026 年3 月 11 日 11:31

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

辞霜 · 2026 年3 月 11 日 11:35

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

辞霜 · 2026 年3 月 11 日 11:36

obproxy 内存告警这个帖子是不是跟你这个一个问题？

李元锴 · 2026 年3 月 11 日 11:36

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

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

李元锴 · 2026 年3 月 11 日 11:39

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

李元锴 · 2026 年3 月 11 日 11:40

obproxy：4.3.2.0-42 开源版本的debug包从哪里可以获取

李元锴 · 2026 年3 月 11 日 11:45

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

李元锴 · 2026 年3 月 11 日 13:43

obproxy：4.3.2.0-42 开源版本的debug包从哪里可以获取

辞霜 · 2026 年3 月 11 日 14:08

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

辞霜 · 2026 年3 月 11 日 14:48

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

李元锴 · 2026 年3 月 11 日 15:39

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

李元锴 · 2026 年3 月 11 日 15:50

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
