Hi Dave,

Yes there still seems to be a problem.  the new one appears to be subtler than the original.

Are you aware that you can do a smaller number of mcmc steps save the results and then restart the mcmc.
that might be the way to go until this leak is identified.

I have been running my model again for roughly 24 hours with the updated version of glmmADMB that you sent to me. The allocated memory might be a bit smaller but reached again already 5.5 GB. However, I started 10000 iterations this time and not 2000 and cannot tell how far the MCMC ran up to now (can I check that somehow?). Therefore, I am wondering if there might be another memory leak. Or do I, for example, also need to update the package R2admb in case the problem was ADMB related?

 

Best wishes,

Maren

Hi,

Here is a 64 bit windows version of glmmadmb with the fix I put in. YOu should unzip it
and replace the glmmadmb.exe in your R dist and give it a try.

      Cheers,

Good to hear. I hope we can get glmmadmb rebuilt with these changes.

Hi Dave,

 

I just want to let you know that the new version of glmmADMB is performing well in a long MCMC run. The allocated memory doesn’t reach such large sizes anymore.

 

Thanks again for fixing the memory leaks!

 

Best wishes,

Maren
