Strange behaviour of .lookup Method

[CCTimeO]

Hello,

can you help me with my Problem?

The relevant parts of my VCL are:

    new dbISP = geoip2.geoip2("/etc/varnish/geoip/GeoIP2-ISP_20150915/GeoIP2-ISP.mmdb");
    new dbCity = geoip2.geoip2("/etc/varnish/geoip/GeoIP2-City_20150324/GeoIP2-City.mmdb");

and

       set req.http.X-GeoIP-ISP = dbISP.lookup("isp", std.ip(req.http.X-Forwarded-For,"0.0.0.0"));
       set req.http.X-GeoIP-CountryCode = dbCity.lookup("country/iso_code", std.ip(req.http.X-Forwarded-For,"0.0.0.0"));
       set req.http.X-GeoIP-City = dbCity.lookup("city/names/de", std.ip(req.http.X-Forwarded-For,"0.0.0.0"));
       set req.http.X-GeoIP-Region = dbCity.lookup("subdivisions/0/names/de", std.ip(req.http.X-Forwarded-For,"0.0.0.0"));

In every 5th -10th request i'm getting a strange result like this:

-   ReqHeader      X-GeoIP-ISP: Deutsche Telekom AGK
-   ReqHeader      X-GeoIP-CountryCode: DEkom AGX-GeoIP-CountryCode:
-   ReqHeader      X-GeoIP-City: Heilbronn
-   ReqHeader      X-GeoIP-Region: Baden-Württembergden-W▒X-GeoIP-Region: X-GeoIP-Region: Baden-Württemberg

I want to do a ISP and city query. I'm using the current databases of my maxmind subscription. Do you have a hint for me or is this a bug?

Kind regards, Timo

Which revision are you using? It looks like I introduced a bug in commit 4b3474fb12878201cd73e61c887ef086cf4cc72d.

I've downloaded & compiled the .zip file today. I think this is the newest commit.

Thanks for the report. It should be fixed on my last commit. Please give it another try and let me know if you find any other issues.

[CCTimeO]

It works now, thank you for your quick help :)

Great to hear that. If you don't mind me asking, are you using this in production?

[CCTimeO]

No problem: Yes, we are using this in our production environment (under heavy monitoring)
