磁盘空间不足; 尝试发送邮件时再试一次

Question

我正在尝试使用 PHP 发送带有附件的电子邮件，但出现此错误：

Insufficient disk space; try again later
Insufficient disk space; try again later
returntosender: cannot select queue for root
Insufficient disk space; try again later
returntosender: cannot select queue for postmaster
queueup: cannot create queue file qfp5M7HeoG001376, euid=51, fd=-1, fp=0x0: No space left on device

我查了一下，好像有空格：

Size  Used Avail Use% Mounted on
112G   89G   18G  84% /
 99M   22M   73M  23% /boot
4.9G   33M  4.6G   1% /tmp
4.9G  4.6G     0 100% /var

我尝试附加的文件小于 4MB。知道这是从哪里来的，我该如何解决？

Answer 1

显然 /var 中没有空间，它将尝试创建线轴
