问题描述
我偶尔会遇到服务器的内存分配限制，尤其是像 Wordpress 这样臃肿的应用程序，但从未遇到过无法为池分配内存"和无法跟踪任何信息的情况.
I've occasionally run up against a server's memory allocation limit, particularly with a bloated application like Wordpress, but never encountered "Unable to allocate memory for pool" and having trouble tracking down any information.
有人知道这是什么意思吗?我试过增加 memory_limit 没有成功.我也没有对应用程序进行任何重大更改.一天没有问题，第二天我就遇到了这个错误.
Does anyone know what this means? I've tried increasing the memory_limit without success. I also haven't made any significant changes to the application. One day there was no problem, the next day I hit this error.
推荐答案
可能与 APC 相关.
对于遇到此问题的人，请指定您的 .ini 设置.特别是您的 apc.mmap_file_mask 设置.
For the people having this problem, please specify you .ini settings. Specifically your apc.mmap_file_mask setting.
对于文件支持的 mmap，它应该设置为:
For file-backed mmap, it should be set to something like:
apc.mmap_file_mask=/tmp/apc.XXXXXX
要直接从/dev/zero 映射，请使用:
To mmap directly from /dev/zero, use:
apc.mmap_file_mask=/dev/zero
对于符合 POSIX 的共享内存支持的 mmap，请使用:
For POSIX-compliant shared-memory-backed mmap, use:
apc.mmap_file_mask=/apc.shm.XXXXXX
