Option to set TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES Use "ceph_tcmalloc_max_total_thread_cache" to set the TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES value inside /etc/default/ceph for Debian installs, or /etc/sysconfig/ceph for Red Hat/CentOS installs. By default this is set to 0, so the default package value will be used, if specified this value will be changed to match the variable, and ceph osd services will be restarted.
