R help - Sep 2011 - cannot correct step size, geweke.diag of coda

Intermittently I'm getting this error from the geweke.diag function of 
the coda package.  Would anyone be kind enough to enlighten me as to the 
possible source of such an error, or how to debug/locate it?

Error in { : task 22 failed - "inner loop 1; cannot correct step size"

Thanks a bunch.
