Hi Eliezer, Thanks for your response, please find the answers below. what are the machine specs? Machine on which Squid is running, is VM having 2 cores and 8 GB of memory. why are you using so many ufs cache dirs? is there a reason? Yes, our purpose is to cache more than 50M json objects. Tried running with single cache directory. that didn't work, after 10-15 days Squid will stop responding with below error in cahce.log. "assertion failed: filemap.cc:76: "fm->max_n_files <= (1 << 24)" I came across work around for the above issue on internet, that mentioned having multiple cache directories.
