The initialization of the class failed because somInitMIClass defined by SOMMSingleInstance is in conflict with another metaclass that has overridden somNew. That is, some other metaclass has already claimed the right to return the value for somNew.

Metaclass Framework Error Codes

It is possible to receive the following messages from the Metaclass Framework while an application is running.

60001
An attempt was made to construct a class with SOMMSingleInstance as a metaclass constraint. (This may occur indirectly because of the construction of a derived metaclass). The initialization of the class failed because somInitMIClass defined by SOMMSingleInstance is in conflict with another metaclass that has overridden somNew. That is, some other metaclass has already claimed the right to return the value for somNew.
60002
An attempt was made to construct a class with SOMMSingleInstance as a metaclass constraint. (This may occur indirectly because of the construction of a derived metaclass). The initialization of the class failed because somInitMIClass defined by SOMMSingleInstance is in conflict with another metaclass that has overridden somFree. That is, some other metaclass has already claimed this right to override somFree.
60004
An invocation of somrRepInit was made with a logging type other tha `o' or `v'.
60005
The sommBeforeMethod or the sommAfterMethod was invoked on a SOMRReplicableObject whose logging type is other than `o' or `v'. This error cannot occur normally. The likely cause is that some method invoked on another object has overwritten this object's memory.
60006
A Before/After Metaclass must override both sommBeforeMethod and sommAfterMethod. This message indicates an attempt to create a Before/After Metaclass where only one of the above methods is overridden.
