gitlab 无法查看提交的文件Errno::ENOMEM (Cannot allocate memory - /opt/gitlab/embedded/bin/git):

更新时间：2022-04-25 11:06:14

　　gitlab可以成功clone和push，但是提交后的文件却无法查看。从页面上看的话只显示出500错误。

　　查了下gitlab的日志

tail -f /var/log/gitlab/gitlab-rails/production.log

　　显示如下异常：

　　查了下内存为2G，已经满足gitlab最小内存1G的要求。

[root@xxxxxx ~]# free -h
             total       used       free     shared    buffers     cached
Mem:          1.8G       1.7G        63M        43M       9.7M       140M

Swap:           0B         0B         0B

　　但是非常诡异的是swap为0，网上找了发现也有人遇到相应的问题。于是修改下swap的大小

[root@xxxx ~]# free -h
             total       used       free     shared    buffers     cached

　　修改后再次查看，果断地出来了，记录于此。
