Mapserver error logging

[Bart van den Eijnden]

Hello list,

I usually use the MS_ERRORFILE environment variable to have Mapserver
output errors to the Apache error log.

Using Mapserver 4.2 most of the error messages seem to be like (in the
past months):

msBuildPath: Unable to access file.
msInsertHashTable: Hash table error. Invalid hash table or key

So the log becomes very large while these errors don't seem to be fatal
though.

Did anybody experience the same? What are they caused by normally? Should
they be reported in error mode or only in debug mode?

Best regards,
Bart
