CV hanging

[tle003]

We have been attempting to do cross-validation with values determined from the 'prime' analysis; however, the analysis gets stuck (crashing my computer), appearing to be going in circles, printing this sort of thing to the terminal:

after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS
result: 4
after opt calc1: 42151.164
setting NLOPT: LD_LBFGS
result: -1
after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS
result: 3
after opt calc1: 42151.164
setting NLOPT: LD_LBFGS
result: 3
after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS
result: 3
after opt calc1: 42151.164
setting NLOPT: LD_LBFGS
result: -1
after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS
result: 4
after opt calc1: 42151.164
setting NLOPT: LD_LBFGS
result: 3
after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS
result: -1
after opt calc1: 42151.164
setting NLOPT: LD_LBFGS
result: -1
after opt calc2: 42151.165
exit siman: 42151.165
setting NLOPT: LD_LBFGS

Note how the decimals are only ever .164 or .165.

Additionally, the output files stop writing.

The optimization parameters are as follows:
nthreads = 10 opt = 1 moredetail optad = 1 moredetailad optcvad = 1 moredetailcvad

I had previously did the same analysis using a preliminary phylogeny, but with slightly different optimization parameters:
nthreads = 10 opt = 2 moredetail optad = 2 moredetailad optcvad = 1 moredetailcvad
This preliminary analysis runs fine, the only difference being a couple of parameters and a slightly different starting tree.

Hi,
were you able to solve that problem? I have a similar problem and it would be great if you could share your solution (if you have one :-))

Best wishes,
Belinda

Just in case anyone else has this issue, here's how I solved it just now. Initially, priming told me to add the following lines:
opt = 5
moredetail
optad = 2
moredetailad
optcvad = 2

and randomcv was taking hours (for my other 9 trees of the same size or larger, it would take minutes at most). All I did was delete those lines and add prime at the end to reprime it. This time it told me to add:
opt = 5
optad = 5
optcvad = 2

instead of the moredetail options. I added those lines and ran it with randomcv and it finished in minutes without an issues. Hope this helps someone!
