Linux系统中，内存占用无法释放的问题

[Gaubee]

执行了release。/dev/shm下面的文件确实也减少了，文件夹大小也减少了。 但是在执行df -h的时候，发现/run/shm的占用一直在增加，直到进程关闭了，才能释放。

you should definitely write standalone script to delete it manually. the share-mem opener have no responsibility to maintain the hook, 'coz it could be killed (for e.g. by root or some admin) at anytime.

是的，就像linux磁盘的inode引用计数一样，共享内存空间直到最后一个引用被删除后(包括/dev/shm，通常需要重启或手动release或rm)才会被释放。
