multiple errors when using glmmADMB

Hi all,

I was trying to use the glmmADMB package but ran into some errors. I?ve
noticed that other people have run into similar errors but there doesn?t
seem to be a solution online. It would be great help if anyone could
provide any insights on it.

I am using it for running a zero-inflated mixed-effects binomial model.
The errors are as follows:

Parameters were estimated, but standard errors were not: the most likely
problem is that the curvature at MLE was zero or negative
Error in glmmadmb(breeding.success ~ laying.date.julian.day.zscale +
tmean.zscale +  :
  The function maximizer failed (couldn't find parameter file)
Troubleshooting steps include (1) run with 'save.dir' set and inspect
output files; (2) change run parameters: see '?admbControl';(3) re-run
with debug=TRUE for more information on failure mode
In addition: Warning messages:
1: In glmmadmb(breeding.success ~ laying.date.julian.day.zscale +
tmean.zscale +  :
  non-integer response values in discrete family
2: running command './glmmadmb -maxfn 500 -maxph 5 -noinit -shess' had
status 1

Any kind of help will be greatly appreciated.
