MsgBuilder Node - 250 Chars Limit - Help

We are in the midst of doing our upgrade from 8.0.3 to 9.0. We are on the AS400 platform.

We have several process flows where we use the MsgBuilder node to build up a string variable with a list of PO's or Req's or whatever it maybe that the flow is iterating through. At the end of the flow we use the MsgBuilder variable in an email node to notify someone of all the PO's or Req's that were processed.
In version 9 now we are getting warning errors that these MsgBuilder variables exceed 250 chars.
Today I looked at the log of one of these flows and it shows this warning message. However the problem is that it did NOT send out the email notification!

Lawson has an article in the KB on this issue, Article ID:5423996. This basically describes the problem I just outlined above, but provides no resolution on how to work around this!

Has anyone else run into this issue, if yes, how do you workaround this?

Please let me know.
