We discussed this at the Hackfest AIG session. A "Max Vendor PO Name Length" might work to prevent this issue overall, although consortia/libraries would need to pay attention to the line item numbers for length (e.g. Line Item IDs 999999 and 1000000).
I suspect that changing the Attribute Set so that the Purchase Order Name doesn't get sent to vendors, also mentioned as a potential solution, wouldn't be popular with our libraries.
