Greetings,

   I'am using PVMegaPOV for rendering animations and it loks like there 
is some memory leak: as it computes more and more frames is takes more 
and more memory. It is very unhappy, because I use some machines with 
64MB RAM and animation, which has at the begining several MB in RAM can 
easily use 100 or 200 MB of RAM when computing 100th frame, for example.

Regards

Disnel

I believe all the current versions have this leak.  I think the only
thing you can do is render a certain number of frames and restart POV. 
Which means you can't have it render while you're gone too.  :(

Exactly, this is the problem. A second, I hanged up all machines in institute,

because they has small amout of swap+memory and I forgot this bug :(((...

Well, if your sys admin is like the one we had at school, you just won
your ticket for a free, 2 hours long speech about Good and Evil. Sorry
;-)

About your problem, could you first give me some more clues (of course
pvmegapov and pvm versions, and OS as usual), and tell me is you get the
same ting with the old pvmpov (after povray 3.1g), and (as was
suggested) with megapov itself?
I used to have problems with the whole scene being added to the object
list instead of replacing it with an old version.

Bye!

No problem, I was there for two weeks and now I'am using machine with my 
configuration and big swap ;-)

pvmegapov 010311, pvm 3.4.3, OS Linux RedHat 6.2.

I don't remember about  old pvmpov, but I think, that it had similar 
problem....

Practial example: this scene

background {color rgb 0.7}

torus {
   10, 1
   pigment {color rgb <0.5, 1.0, 1.0>}
   finish {ambient 0.3 diffuse 0.7}
}

sphere {
   <0, 2*sin(10*pi*clock), 0>, 3.0
   pigment {color rgb <1.0, 0.5, 0.5>}
   finish {ambient .3 diffuse .7}
}

camera {
   location <-30, 40, -30>
   right <1, 0, 0>
   up <0, 1, 0>
   direction <0, 0, 1>
   angle 30
   look_at <0, 0, 0>
}

light_source {< 100, 100, -50> color rgb 1.0}
light_source {<-100, 100, -50> color rgb 0.3}

Starts with stats

   PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME
  2046 disnel     8   0  3180 3180   836 R       0 53.6  0.3   0:02 mp
  2047 disnel    14   5  4548 4548  1200 R N     0 47.9  0.4   0:02 mp
  2048 disnel    13   5  4480 4480  1200 R N     0 45.1  0.4   0:02 mp

And end with stats

   PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME
  1986 disnel     8   0 10236   9M   840 R       0 50.3  1.0   1:46 mp
  1988 disnel    12   5  140M 140M  1200 R N     0 49.7 14.7   1:51 mp
  1987 disnel    12   5  137M 137M  1200 R N     0 48.5 14.5   1:52 mp

at 500th frame.
