Default DESeq-biological replicates differ between groups

I test for differential expression genes, where I have 6 biological replicates in one condition and 18 in the other.

When I use the "estimateDispersions" , it gives me the following error:

>cds <- estimateSizeFactors(countdata)
>cds <- estimateDispersions(cds)

Warning:
In parametricDispersionFit(means, disps) : Dispersion fit did not converge.

Do you know why this warning arise?
