Jim, Have you tried running the same rrdtool graph command with a different image format for your output (alternatives are EPS, SVG, and PDF; see the --imgformat parameter). If rrdtool can render to these other formats, that helps narrow down the problem. Also, follow the tutorial on the rrdtool website. Are those graphs rendered or do you receive the same error? This will help determine if this is a general problem with the library (or interaction between librrd, libpng, and zlib) or if it's an inconsistent problem that may be caused by improper memory allocation, insufficient buffer length, etc. -Sam _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
