新部署了一个项目，最近发现php-fpm错误日志很多
child 5883 exited on signal 7 (SIGBUS) after 9.246067 seconds from start
child 5909 started
......
之类的子进程崩溃重启信息，随机跟踪几个php-fpm子进程，发现都是到一处停下来了
stat("./Apps/Runtime/common~runtime.php", {st_mode=S_IFREG|0644, st_size=86142, ...}) = 0
getcwd("/home/wwwroot/data", 4096) = 19
open("/home/wwwroot/data/Apps/Runtime/common~runtime.php", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0644, st_size=86142, ...}) = 0
fstat(4, {st_mode=S_IFREG|0644, st_size=86142, ...}) = 0
fstat(4, {st_mode=S_IFREG|0644, st_size=86142, ...}) = 0
mmap(NULL, 86142, PROT_READ, MAP_SHARED, 4, 0) = 0x7fb3f975f000
--- SIGBUS (Bus error) @ 0 (0) ---

这个文件的写权限是有的，请教一下问什么到这里都有很大几率会导致处理进程崩溃？谢谢。
