BEAST - JAVA error or not?

[Garima]

Hi,

I have been trying to run BEAST 2.6.6 for 100 +million generations (data contains 23 taxa (including 1 outgroup) for a length of 24.8 kb DNA sequence, on computer with 8 GB RAM and 3.4 Hz processor. I haven't had success so far owing to the following error:

   10710000    -40633.9022        27.8       -40552.5612       -81.3410 37m5s/Msamples

It keeps happening. I have tried to run it on a Linux based system with 64 GB RAM and 1 TB space too. But my efforts were to no avail. Can anybody help me?

Indeed, it looks like java ran out of memory. To increase available memory, see here: http://www.beast2.org/increasing-memory-usage/
