What steps will reproduce the problem? I have compiled rtg and rtgplot on a Debian 5.0.4 box. Everything work fine and I am monitoring a single box. When using the new web interface for the new version of rtgplot.cgi it generates the graphs correctly but logs the above error message and about 500 lines of stack trace. What is the expected output? What do you see instead? The graphs look fine, but it just products 500 lines of error in the error logs. What version of the product are you using? On what operating system? The latest check out from SVN, on debian 5.0.4. Please provide any additional information below.

I think I saw the same issue on a 64 bit Fedora 14 machine (It was a while ago and I don't have the logs any more)

I created the attached patch which seems to fix the issue (I'm not sure if it's a good fix). I think it was partly based on an older discussion of a similar problem on the mailing list.

Tested this on my x86_64 installation (CentOS5). Compiles fine, appears to fix the error. Any other testers?

Upgrading and re-compiling for Debian Squeeze seems to fix the problem :/

For me the patch work fine in Debian 5.0.8 64bits.

Daniel have you though to reinstall the libmysqlrtg with the "make install-libLTLIBRARIES" ? Without the lib replacement the problem still exist.

If i have no response or comment i will apply the patch in the trunk. The code is better and respect the MySQL api docs.
