Hello guys/devs,

I realized that my games are taking over 1 gig of ram each, is that normal ?

here the result from 'top' command : 
  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND

  784 tacgnol   20   0 1928224 1.071g   6092 S  12.6 13.8 270:43.50 doomsday-server

Also, is there a way to check deeper what could cause this, any type of log ?

    That does seem rather excessive. Servers shouldn't be loading any large resources or allocating large buffers since they don't draw any graphics... I'll need to start a few servers of my own and inspect their memory use.

    Each server does output the usual doomsday.out log, but that probably doesn't contain much useful information to diagnose this issue.

    Which version/build of Doomsday are you using for these?
  • tacgnoltacgnol
    i'm using the latest build 2829. config is pretty much the same as my other thread.
  • skyjakeskyjake
    Took a little while, but I found one memory leak in the server. It has been fixed for the next build.
  • tacgnoltacgnol
    I upgraded the server yesterday. I will report in a couple of days if it's better.


    thanks again !

    so far so good !

    the ram usage did not increase :)

    Something happened between the 2.1.0 official build and some of the latest 2.1.1 build.

    The memory was going pretty high, 800MB + per instance.

    I reverted to 2.1.0, and everything seems to be good. between 100-200 MB per instance, steady.

    edit : i might be wrong ... hold on ....
