In the cases that are failing, did you get fairly extreme
parameter estimates (e.g. |beta|>5)? If so, then I suspect that
you're encountering the same problem as documented in
https://github.com/lme4/lme4/issues/124
As Steve Walker says, a reproducible example would help (and
would increase the priority of this issue).
