Hi, we're experiencing exactly the same issue using the local filesystem as cache store. We had the same issue with nginx 0.7.67 and now with 0.8.54. The cache grows outside the specified boundaries and nginx process uses the 100% of a single core. I tried to strace the malfunctioning running process but all I got is tons of gettimeofday gettimeofday({1300181425, 698292}, NULL) = 0 gettimeofby nettie - Nginx Mailing List - English
