问题描述
我们让 Jenkins 在 ec2 实例上运行.在进行构建时，我们看到以下错误:
We have Jenkins running on an ec2 instance. When doing a build, we see the following error:
17:29:39.149 [INFO] [org.gradle.api.Project] OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000007ac000000, 234881024, 0) failed; error='Cannot allocate memory' (errno=12)
17:29:39.150 [INFO] [org.gradle.api.Project] #
17:29:39.150 [INFO] [org.gradle.api.Project] # There is insufficient memory for the Java Runtime Environment to continue.
17:29:39.150 [INFO] [org.gradle.api.Project] # Native memory allocation (malloc) failed to allocate 234881024 bytes for committing reserved memory.
我研究了这个主题并尝试了各种设置，例如增加堆内存、ram 和 PermGenSize.这是我当前在 Jenkins 上的内存设置:
I researched on this topic and tried various settings such as increasing the heap memory, ram and PermGenSize. Here is my current memory setting on Jenkins:
-Xms256m -Xmx2048m -XX:MaxPermSize=512m
还有其他我遗漏的东西会导致 OOM 吗?
Are there any other things that I'm missing that's causing an OOM?
推荐答案
我也遇到过同样的问题.(我有 ec2、t2.micro、Ubuntu 14、Jenkins、Tomcat、Maven).默认情况下，您没有交换空间.要确认这一点:
I've sold the same problem. (I have ec2, t2.micro, Ubuntu 14, Jenkins, Tomcat, Maven).By default you don't have swap space.To confirm this:
free -m
添加一些.开始尝试使用 1 GB.
Just add some. Try with 1 GB for begin.
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
再次检查:
free -m
