Hi, everyone ... hope I'm missing something simple here. Sorry for the length of this email, I wanted to make it clear that I've tried pretty hard to solve this on my own, with no luck. I've looked through the mailing list archives, and the closest I've seen to my problem is ...

The system is a Sun X2200 M2, 2x 1.8 GHz Opteron processors, running RHEL 4u4 X86_64. All of the pieces of rrdtool and the libraries it uses were compiled from source, on this system, following the instructions on the rrdtool website. I'm having problems getting smokeping.cgi working. The daemon process is running fine, but when I try to load the smokeping.cgi script, I get: [Sat Apr 07 16:53:53 2007] [error] [client 171.66.16.78] [Sat Apr 7 16:53:53 2007] smokeping.cgi: Can't load '/usr/local/lib/perl/5.8.5/ x86_64-linux-thread-multi/auto/RRDs/RRDs.so' for module RRDs: librrd.so.2: failed to map segment from shared object: Cannot allocate memory at /usr/lib64/perl5/5.8.5/x86_64-linux-thread-multi/ DynaLoader.pm line 230.

I've eliminated SpeedyCGI as the culprit; I get the same effect whether the shebang line is #!/usr/ bin/perl or #!/usr/bin/speedy. The weird thing is that I have no problem running the script from the command-line, as the user that the webserver is running as: [EMAIL PROTECTED] ~]$ ~smokeping/public_html/smokeping.cgi ### fping seems to report in 1 milliseconds Expires: Sun, 08 Apr 2007 00:04:09 GMT Date: Sat, 07 Apr 2007 23:59:09 GMT Content-Type: text/html; charset=iso-8859-15 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <META HTTP-EQUIV="Cache-Control" content="no-cache"> <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Refresh" CONTENT="300"> <TITLE>SmokePing Latency Page for smokeping</TITLE> ( ... snip ... ) ... and I have no problem in general with the RRDs; the following test script works both from the command line and via the webserver: ############################################################## #!/usr/bin/perl -w # -*-perl-*- use lib qw(/opt/home/smokeping/lib); use lib qw(/usr/local/lib/perl /usr/local/lib/perl/5.8.5 /usr/local/ lib/perl/5.8.5/x86_64-linux-thread-multi); use CGI::Carp qw(fatalsToBrowser warningsToBrowser); use strict; use CGI; use RRDs; #use Smokeping 2.000009; my $cgi = new CGI; print $cgi->header; print "<html><head></head><body>\n"; RRDs::create ("/tmp/test.rrd", "--step", "300", "DS:foobar:COUNTER:1800:0:4294967295", "RRA:AVERAGE:0.5:1:2016"); my $ERR = RRDs::error; if ($ERR) { print "RRDs::create error was: $ERR\n<br><br>" } else { my $hash = RRDs::info "/tmp/test.rrd"; foreach my $key (keys %$hash) { print "$key is $$hash{$key}\n<br>"; }; }; print "</body></html>\n"; ############################################################# ... but if I *uncomment* the "use Smokeping 2.000009" line in the above script, I get this error in the error_log ...
