Error in splm random effects ML model

Dear community,
I am trying to run a spatial panel random effects SEM model using splm
package on a balanced spatial panel of N = 2472 and T = 4, and weights
are based on k = 6 nearest neighbors. I encounter this error, which I
can't find anything about in the documentation or online.

Error in .C64("aplsb1", SIGNATURE = c(SS$signature, SS$signature,
"double", :?NAs in argument 7 and 'NAOK = FALSE' (dotCall64)
Please at least provide the output of traceback() after the error (it does not crash, it error-exits correctly). Also provide the output of sessionInfo() - versions of underlying packages may matter (I'm thinking of dotCall64 and packages it uses). .C64() is not called by splm functions directly. Does the error persist on a fully updated system on the same OS? What happens on a different platform if available? Ideally, provide a fully reproducible minimal example using built-in data, or provide your data and the code used to create analysis.subset and listw.wgts, so that the running the code creating the error can be reproduced exactly. The error message reports NAs, are the data complete? Roger
Unlike the same specification but with fixed effects (with model = "within" argument), the one above takes a long while to run until it crashes. As far as I can tell, there are no memory issues. An alternative spatial random effects using spgm() command runs OK, as do non-spatial fixed and random effects models using plm(). For the one above I could use spgm(), but I would prefer to keep all my models in the maximum likelihood estimation for consistency. Any clarifications as to the nature of the error are welcome.? Thank you. Denys Dukhovnov
