Because the GC log is written to /dev/shm, the /dev/shm disk usage reaches 100% | 因gc日志写入/dev/shm，导致/dev/shm磁盘使用率达到100%

The default /dev/shm space for containers is only 64MB, and it's used up by garbage collection (GC) logs in less than a month. It doesn't seem to be automatically deleted, and when it's full, new GC logs can't be written. Why are GC logs written to /dev/shm/? Can this be changed?
容器默认的/dev/shm空间只有64M，一个月不到就会被gc日志用完。看起来不会自动删除，满了新的gc日志就写不进去了。那gc日志为什么要写入/dev/shm/？是否可以更改？
