Description

I have 100 file, 0.mp4, 1.mp4 ... 99.mp4, every file`s size is 1M

records.config

proxy.config.cache.target_fragment_size INT 1048576

I use curl to get them :

  for((i=0;i<100;i++)); do curl -v -o /dev/null http://www.test.com/testdir/$i.mp4; done

every file just get once, i can see ats memory usage is 138M

After use curl to purge them :

for((i=0;i<100;i++)); do curl -v -o /dev/null -X purge http://www.test.com/testdir/$i.mp4; done

I can see ats memory usage is 246M
every file removed from ats, why the memory usage enlarge about 100M
