 OOM 是操作系统的保护机制，当操作系统内存(包括 SWAP )不足时，会杀掉某些进程，从而保证操作系统的稳定运行。通常内存不足主要是如下两个原因导致，一是剩余内存小于 vm.min_free_kbytes ；二是程序请求的内存大于剩余内存。还有一种情况是内存充足但程序占用了特殊的内存地址，也会触发 OOM 。
 
 TDengine 会预先为每个 VNode 分配好内存，每个 Database 的 VNode 个数受 建库时的vgroups参数影响，每个 VNode 占用的内存大小受 buffer参数 影响。要防止 OOM，需要在项目建设之初合理规划内存，并合理设置 SWAP ，除此之外查询过量的数据也有可能导致内存暴涨，这取决于具体的查询语句。TDengine 企业版对内存管理做了优化，采用了新的内存分配器，对稳定性有更高要求的用户可以考虑选择企业版。

+### 19. 在macOS上遇到Too many open files怎么办？
+
+taosd日志文件报错Too many open file，是由于taosd打开文件数超过系统设置的上限所致。
+解决方案如下：
+1. 新建文件 /Library/LaunchDaemons/limit.maxfiles.plist，写入以下内容(以下示例将limit和maxfiles改为10万，可按需修改)：
+```
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
+"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+<dict>
+<key>Label</key>
+  <string>limit.maxfiles</string>
+<key>ProgramArguments</key>
+<array>
+  <string>launchctl</string>
+  <string>limit</string>
+  <string>maxfiles</string>
+  <string>100000</string>
+  <string>100000</string>
+</array>
+<key>RunAtLoad</key>
+  <true/>
+<key>ServiceIPC</key>
+  <false/>
+</dict>
+</plist>
+```
+2. 修改文件权限
+```
+sudo chown root:wheel /Library/LaunchDaemons/limit.maxfiles.plist
+sudo chmod 644 /Library/LaunchDaemons/limit.maxfiles.plist
+```
+3. 加载 plist 文件 (或重启系统后生效。launchd在启动时会自动加载该目录的 plist)
+```
+sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist
+```
+4.确认更改后的限制
+```
+launchctl limit maxfiles
+```
