Dependencies
- libevent, https://www.monkey.org/~provos/libevent/ (libevent-dev)
- libseccomp, (optional, experimental, linux) - enables process restrictions for better security. Tested only on x86_64 architectures.
Environment
Be warned that the -k (mlockall) option to memcached might be dangerous when using a large cache. Just make sure the memcached machines don't swap. memcached does non-blocking network I/O, but not disk. (it should never go to disk, or you've lost the whole point of it)
Bug reports
Feel free to use the issue tracker on github.
If you are reporting a security bug please contact a maintainer privately.
