loading, the loading fails and no operations are possible until the 
problem is corrected. If the error occurs later, during normal 
operations, there are some additional issues to consider.
If the MicroKernel is already loaded when an error occurs creating 
the transaction log file, it ceases transaction logging; however, the 
MicroKernel attempts to resume transaction logging after every 
update to a data file containing system data. Therefore, when the 
condition causing the error is corrected (for example, when more 
disk space is made available), the MicroKernel automatically 
resumes transaction logging. 
MKDE-75: The log file format is invalid
The MicroKernel returns this message when the log segment file 
format is incompatible. Ensure that the version of the MicroKernel 
doing the roll forward is the same as the version of the MicroKernel 
that created the log file.
MKDE-76: An Open operation failed on “xxxx” with MKDE 
error nn
The MicroKernel returns this message during roll forward

MKDE-77: An unexpected MKDE error nn occurred on 
INSERT to “xxxx”
The MicroKernel returns this message during roll forward 
operations when an Insert error occurs. The MicroKernel returns the

Codes for a description of Status Code nn.
MKDE-78: An unexpected MKDE error nn occurred on
