You have given us no data to diagnose your problem. What do you mean
by "cannot handle" -- does the package print a message "no 3 way
interactions", gives wrong answers, your laptop catches on fire when you
run it, ....?
Also, make sure you read help(frailty). The following is a key line
"Use of gamma/ml or gaussian/reml with survreg does not lead to valid
results."
