In the last few days, I've been bitten by JAGS crashing, usually taking R down
with it. The models aren't enormous, and this happens both in 32-bit and
64-bit R/JAGS. Unfortunately, I haven't been able to reproduce this
Martyn, is there a way to run JAGS from R in a way that captures a dump or
other information that would be useful for you for debugging? This is on
It can be done, with some difficulty.
The only time I've crashed JAGS/R in Windows was by asking for too much
memory. This generally had more to do with monitoring many nodes for many
iterations, rather than the total number of nodes in the model. However, my
experience is that too-much-memory crashes were reproducible, so that may not
be what is going on with you. Just out of curiosity, was there any sort of
error message? What did it say?
Nope, no error message, and not an out-of-memory issue. Just a very unhappy R
process. Useless answer, I know.
If you send me your programs and data confidentially I will debug it under
Linux. There are a number of powerful tools that can be used (dbx, valgrind).
