cacheman.lock.bad and cacheman.shm.bad files

[ayaz]

I am seeing the following `.bad` versions of `.cacheman.lock` and `.cacheman.shm` files inside the cache storagePath. Can someone please help me explain what they represent and what can cause them to show up?

# ls -al
total 156
drwxrws---  3 nobody nogroup  4096 Apr 22 14:42 .
drwxrwxrwx  4 root   root     4096 Apr 21 10:29 ..
-rw-r-----  1 root   nogroup  8192 Apr 23 17:32 .cacheman.lock
-rw-r-----  1 root   nogroup  8192 Apr 22 07:17 .cacheman.lock.bad
