# 现象

2026-03-16: 早上客户发现我司 Web 系统登录不上, reboot 重启服务器恢复业务

reboot 之后, 一线收集了巡检信息返回到研发这边, 需要研发分析出现异常的原因.

分析过程

第一阶段

2026-03-16: 根据收集回来的信息, 发现没有 messages 日志, pg_log 目录下的日志显示.

可以看到 select 1 就耗时了310416.988 ms 显然不正常

再往前面查看

ounter(lineounter(lineounter(lineounter(line2026-03-15 23:39:38.731 UTC     2106:LOG:  checkpoint starting: time2026-03-15 23:40:12.231 UTC     2106:LOG:  checkpoint complete: wrote 270 buffers (0.2%); 0 WAL file(s) added, 0 removed, 0 recycled; write=29.756 s, sync=3.235 s, total=33.501 s; sync files=168, longest=0.287 s, average=0.020 s; distance=3710 kB, estimate=4382 kB2026-03-15 23:45:55.167 UTC [unknown] postgres 192.168.100.201(58750) cds 8087:LOG:  duration: 6265.354 ms  statement: SELECT sys_account_id, dir_code, dir_name, total_cap, spare_cap, pool_id, sys_account_type, full_policy, dir_attr, from_dir_code  FROM tbl_cds_usr_dir_info  ORDER BY dir_attr ASC , dir_code asc limit 100000 offset 0;2026-03-15 23:46:02.823 UTC [unknown] postgres 192.168.100.201(58746) cds 8086:LOG:  duration: 6534.802 ms  statement: SELECT COUNT(1) FROM tbl_bm_group_info ;

可疑的 SQL 如下

ounter(lineSELECT sys_account_id, dir_code, dir_name, total_cap, spare_cap, pool_id, sys_account_type, full_policy, dir_attr, from_dir_code  FROM tbl_cds_usr_dir_info  ORDER BY dir_attr ASC , dir_code asc limit 100000 offset 0;

耗时 6s , 也不太正常. 但是没看是否是这条 SQL 导致的. 没有其他明显信息

没有 sar 信息, 没有 messages 信息

第二阶段

2026-03-17: 二线申请了远程, 我作为研发 DBA 远程上去额外收集了下 sar 信息与 messages 信息, 用于分析

分析过程如下:

查看负载

sar -f /var/log/sa/sa16 -q

可以看到问题发生的时间点 08:05:47 附近, 这个时候负载巨高, 从 8.7 直接激增为 1595, 后面知道下午 04:47:49 负载都在一千多

主要是 CPU 导致的? 还是 IO 导致的? 接着分析

查看 CPU 占用

sar -f /var/log/sa/sa16 -u

可以看到08:05:47 这个时间点统计到的 CPU 占用情况是, 系统占用 86.68% , 用户占用 2.1% ,idle 为 6.33%, 说明主要是系统在消耗 CPU, 系统可能有啥问题

查看硬盘占用

sar -f /var/log/sa/sa16 -d

可以看到 tps 明显变大, 读磁盘的速度明显变高, 磁盘使用率 util 明显变高.

说明此时, 磁盘读使用率也挺高.

再查看下内存使用情况

sar -f /var/log/sa/sa16 -r

查看下 page 页占用情况

sar -f /var/log/sa/sa16 -B

结合 sar -r 与 sar -B 可以看到 08:05:47 这个时间点 pgpgin 高达 108313 个页(每个页 8k) 从硬盘换入到 os page buffer 中, 也说明存在大量的读硬盘, 而是 pgscank 与 pgscand 表明此时内存不足, OS 在做内存回收, 后续几个小时直到下午 03:16:54 也大都处于内存不足状态(下面三点多, 客户 reboot 服务器了)

分析如下:

🔍 sar -B 字段含义

字段	含义
pgpgin/s	每秒从磁盘换入的页数
pgpgout/s	每秒换出到磁盘的页数
fault/s	每秒缺页中断次数
majflt/s	每秒主要缺页（需要磁盘I/O）
pgfree/s	每秒释放的页数
pgscank/s	每秒扫描的页数
pgscand/s	每秒直接扫描的页数
pgsteal/s	每秒被"偷走"的页数
%vmeff	扫描效率

🔍 08:45:47 时间点详细分析

⚠️ 内存交换状态

指标	数值	分析	状态
pgpgin/s	108,113	每秒换入 10.8万页	⚠️ 极高
pgpgout/s	98.60	每秒换出 99 页	正常
majflt/s	5,962.20	每秒主要缺页	⚠️ 高
pgscank/s	342,921	每秒扫描 34万页	⚠️ 极高
%vmeff	2.71%	扫描效率	⚠️ 极低

📊 问题分析

1. 内存严重不足

pgpgin/s 108,113 → 每秒需要换入 10.8万页（约 420MB）
majflt/s 5,962 → 每秒 5,962 次需要磁盘I/O的缺页
说明： 内存不够用，频繁从磁盘换入数据

2. 换页效率低下

%vmeff 2.71% → 只有 2.71% 的扫描是有效的
说明： 系统在疯狂扫描内存，但找到的可用页很少

3. 可能原因

内存泄漏
应用内存需求暴增
系统缓存过大
内存不足 + 大量并发进程

另外, 可以看到从 07:40 到 08:05 期间, 正常应该有 07:50, 08:00 两个点的统计信息, 但是此环境中没有

说明此时由于系统负载过高, sar 统计进程都没有正常收集信息了

说明 07:40 到 08:05 期间负载很高, 已经存在异常了, CPU 占用很高, 磁盘读也很严重, 并且由于 OS page 中数据不在, 频繁读磁盘

与之对应的就是如下大量读 10w 条记录的 SQL

ounter(lineounter(line2026-03-15 23:45:55.167 UTC [unknown] postgres 192.168.100.201(58750) cds 8087:LOG:  duration: 6265.354 ms  statement: SELECT sys_account_id, dir_code, dir_name, total_cap, spare_cap, pool_id, sys_account_type, full_policy, dir_attr, from_dir_code  FROM tbl_cds_usr_dir_info  ORDER BY dir_attr ASC , dir_code asc limit 100000 offset 0;2026-03-15 23:46:02.823 UTC [unknown] postgres 192.168.100.201(58746) cds 8086:LOG:  duration: 6534.802 ms  statement: SELECT COUNT(1) FROM tbl_bm_group_info ;

可以看到此时查询 10w 条, 并且涉及排序, 消耗内存应该不少, 大概率就是这个 SQL 导致的雪崩(压死骆驼最后一根稻草)

该 SQL 对应的业务通过二线与现场用户确认确实有在 07:45 左右操作过, 说得通了.

如果有 oswatcher 可以方便查看到, 但是由于现场环境中没有部署该工具, 无法查看到相关信息

最后分析下系统 messages 日志

可以看到 08:00:45 这个时间后生了 oom-killer, 并且将最消耗内存的 Java 进程给 kill 掉了.

07:40 附近内存已经比较少了, 然后 OS 发生 scank 与 scand 进行 page 页面扫描以回收内存, 应用被阻塞了 ,系统 hang 住了.

回收内存之后发现内存还是比较紧张, 然后继续扫描, 并达到 oom killer 阈值 , 进而触发 oom killer.

从之前的 sar -B 结果可以看到

在08:45:47的时间点，sar -B显示%vmeff=2.71%
用户认为这个数值很低，说明扫描效率极低

我需要解释%vmeff的含义以及2.71%这个数值的意义。%vmeff是内存扫描效率，表示每秒扫描的页数与实际回收页数的比率。通常这个数值应该在合理的范围内，2.71%确实很低，说明内存回收效率很差。

让我详细解释这个概念。

%vmeff=2.71%确实表明内存扫描效率极低，这解释了为什么页面扫描（pgsweep/pgscan）无法有效缓解内存压力。

%vmeff指标解析

%vmeff（内存扫描效率）表示：

每秒实际回收的页数 / 每秒扫描的页数 × 100%
正常情况下应该在10-30%左右
2.71%意味着每扫描100页，只能回收约2-3页

为什么效率这么低？

匿名内存占比高：

应用程序（如Java）使用的匿名内存无法被换出
内核只能回收文件缓存等可换出页面

mlock/madvise限制：

某些进程可能锁定了内存
内核无法回收这些页面

swap空间不足或不可用：

如果swap分区满了或被禁用
内核无法将页面换出到磁盘

内存碎片化：

大量小内存块分散，无法合并成可用的大块

与OOM的关系

这个低效率解释了整个事件链：

ounter(line内存压力 → 页面扫描(低效) → 回收少量内存 → 压力持续 → OOM触发
