Any suggestions for monitoring complex models? As I can see the MultiBUGS is still a 32-bit program, providing warnings (for too many monitors set) would be nice, because losing all the results after a long run is very frustrating.
@helsinkiant has developed a way to solve this problem but it won't be ready for 1.0. For now the only suggestion is to thin more; or draw samples, then export the samples (to coda), then clear the monitors, then draw more samples etc.

Hello Rob one of the new things I have done in MultiBUGS v2 is to change
how sample monitors are implemented. Now the sample values get written to a
disc file. They are then read back into RAM one at a time when summary
statistics are requested. This way memory usage is kept low and I have not
noticed any speed problems.
Can we retro fit the new code into older versions of the software?

Thank you for the advice.
I'll try larger values for the thin parameter to avoid such sampling errors.

This disc based monitor system is implemented in v2.0 in the master branch, so closing. Thanks again for the report.
