There are a bunch of RUNNABLE threads, but sometimes the term "RUNNABLE" in a Java thread dump doesn't actually mean "taking CPU time right now". For example, the "main" thread is RUNNABLE but it's waiting on accepting a socket connection (for a SHUTDOWN command) and so it's effectively blocked, taking zero CPU time. I'm not entirely sure what the Memcached threads actually do, but I think they are in a similar situation: waiting for code to request some communication with Memcached. - -chris > 2015-02-27 16:46 GMT+01:00 Christopher Schultz > <ch...@christopherschultz.net >> : > > Peter, > > On 2/27/15 10:41 AM, Peter Irbizon wrote: >>>> 2015-02-27 16:32 GMT+02:00 Christopher Schultz >>>> <ch...@christopherschultz.net >>>>> : How much memory is in this thing? >>>> >>>> I have one with 700 MHz ARM1176JZ, 512MB RAM (model B).
