PROC VARCLUS on tetrachoric correlation data

I have a large dataset which includes 373 Binary variables (with only two categories).

I need to cluster all the variables through Proc Varclus.
First I run Macro %Polychor for obtaining Tetrachoric correlation coefficients,
and then use the correlation data as input for variable clustering through Proc Varclus.

When running Proc Varclus, a warning in log as the following:
WARNING: Iteration limit exceeded in ALS phase with 5 cluster(s).

Can anybody tell me what I should do?

Thanks.
