Resolution

This has been resolved by disabling the dynamic logmode feature introduced with TPX 5.3:

1. The ability to disable the TPX dynamic logmode feature is available in the base TPX 5.4 product, or in TPX 5.3 when published solutions RO21026 and RO21027 are applied. 
2. Set SMRT Optional Parm #38 = Y to disable dynamic logmode. (Check field level help for this Optional Parameter to ensure it is enabled.) 
3. Cycle TPX.
