Strange errors in Oracle Service Bus

On a previously working code that was exported from an 11g ( OSB domain and imported into the 12c domain we can observe this 2 errors

1. "OSB-382520 Unexpected error executing if-then-else expression".

It seems to happen randomly, under load in perhaps 1 out of several hundred requests. We can run the same identical request through again and it does not occur.

2. The second error is “{bea-err}VAR001: "$xxx": unbound external variable” Where XXX is a variable that has definitely been set prior to where it fails, sometimes even one of the system variable such as $body, $inbound, etc. Even if it wasn’t set, in the past this would evaluate the empty string. Once again, this happens randomly and you can run identical transaction that work, and some that don’t.

{bea-err}VAR001: "$xxx": unbound external variable, OSB-382520 Unexpected error executing if-then-else expression
"OSB-382520 Unexpected error executing if-then-else expression"
