Just to be sure, run make clean and then configure with mmap again (don't forget a make install). Can you send the logfile created by strace -s4096 -o /tmp/rrdtool-trunk.mmap.1.log /there/rrdtool ... You are using pristine trunk, without any additional patches, right? What revision are you using (i assume you're on i386)? thanks, _______________________________________________ rrd-developers mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-developers
