DS 6 memory errors from attribute encryption?

In previous post I am replicating from ds 5.2 to ds 6. Now I have enabled attribute encryption in ds 6 for one attribute. I initialize ds 6 from ds 5.2 and replication completes ok but the ds 6 server stops. I get the memory errors below which I suspect are due to the attribute encryption. Any tuning suggestions or comments?

Yes I will. It appears to be bug 6305434 - Server crash if encrypted attribute exists with no value. This was fixed in patch 5 for 5.2 but may still be an issue in 6.
