Thanks Jose. I'm hoping to test the change in production tomorrow. Oddly, our 
staging server doesn't show the same errors even though it's the same setup. I 
tested the change on staging and didn't see any errors still, so at least that 
bodes well!

Cheers,

Graham

Subject: Re: [dspace-tech] MaxMind GeoLite2-City.mmdb errors

I'm not sure. I have 6.3 and Mirage2 and have the file here:
[dspace]/config/GeoLite2-City.mmdb

I guess that would be an easy thing to test.

Hi there,

This question relates to DSpace 5.10 (XML, Mirage 2) running on Ubuntu 16.04.7 
LTS.

Our logs at /home/dspace/dspace/log/ contain error messages like the following.

ERROR org.dspace.statistics.SolrLogger @ Unable to get location of request:  
The MaxMind DB file's data section contains bad data: invalid size of double.
ERROR org.dspace.statistics.SolrLogger @ Unable to get location of request:  
Unexpected data type returned. The GeoIP2 database may be corrupt.
ERROR org.dspace.statistics.SolrLogger @ Unable to get location of request:  
Something went horribly wrong in the decoder. An extended type resolved to a 
type number < 8 (7)
ERROR org.dspace.statistics.SolrLogger @ Unable to get location of request:  
The MaxMind DB file's data section contains bad data: invalid size of double.

I made sure the mmdb file is working as expected, using the MaxMind tools 
https://github.com/maxmind/mmdbinspect and 
https://github.com/maxmind/mmdbverify.

The config at dspace/config/modules/usage-statistics.cfg set the db's location 
to /usr/share/GeoIP/GeoLite2-City.mmdb. Would it need to be at 
[dspace]/config/GeoLite2-City.mmdb instead?

Cheers,
Graham



Anyone have some pointers in the right direction on how to fix these errors?
