No core file found on file system . system may be configured not to allow creation of one , Not sure , checking , the system IS configure to NOT allow a core file to be produced , I'll try seeing if this will create one , Fyi , It does not produce a core file . Can you help with getting 'gdb' to allow ... # gdb /usr/local/bin/perl /usr/local/mrtg-2/bin/mrtg-ORIG /var/www/htdocs/router2cgi/cfg/to-rtr01.cfg Excess command line arguments ignored.

I am very sure it is the RRDs::updatev call in mrtg causing the 'SegFault' because in order to work arround the issue I have edited mrtg to something like below & it updates just fine . I am running "RRDtool 1.3.6" as you'll see further below . Also 'mrtg 2.16.2' . <my edit to mrtg> # # if ( $RRDs::VERSION >= 1.2 ){ # $rrddata=RRDs::updatev($dotrrd, "$time:$inlast:$outlast"); # } else { # RRDs::update($dotrrd, "$time:$inlast:$outlast"); #} # </my edit to mrtg> # perl -V Summary of my perl5 (revision 5 version 10 subversion 0) configuration: Platform: osname=linux, osvers=2.6.23.12, archname=i686-linux uname='linux dsb-mntr01 2.6.23.12 #1 smp fri dec 28 16:18:35 akst 2007 i686 intel(r) pentium(r) 4 cpu 1.70ghz genuineintel gnulinux ' config_args='' hint=recommended, useposix=true, d_sigaction=define useithreads=undef, usemultiplicity=undef useperlio=define, d_sfio=undef, uselargefiles=define, usesocks=undef use64bitint=undef, use64bitall=undef, uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='cc', ccflags ='-fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64', optimize='-O2', cppflags='-fno-strict-aliasing -pipe -I/usr/local/include' ccversion='', gccversion='4.1.2', gccosandvers='' intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=1234 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=12 ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8 alignbytes=4, prototype=define Linker and Libraries: ld='cc', ldflags =' -L/usr/local/lib' libpth=/usr/local/lib /lib /usr/lib libs=-lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lc perllibs=-lnsl -ldl -lm -lcrypt -lutil -lc libc=/lib/libc-2.5.so, so=so, useshrplib=false, libperl=libperl.a gnulibc_version='2.5' Dynamic Linking: dlsrc=dl_dlopen.xs, dlext=so, d_dlsymun=undef, ccdlflags='-Wl,-E' cccdlflags='-fPIC', lddlflags='-shared -O2 -L/usr/local/lib' Characteristics of this binary (from libperl): Compile-time options: PERL_DONT_CREATE_GVSV PERL_MALLOC_WRAP USE_LARGE_FILES USE_PERLIO Built under linux Compiled at Feb 5 2009 17:17:36 @INC: /usr/local/lib/perl5/5.10.0/i686-linux /usr/local/lib/perl5/5.10.0 /usr/local/lib/perl5/site_perl/5.10.0/i686-linux /usr/local/lib/perl5/site_perl/5.10.0 /usr/local/lib/perl5/site_perl/5.8.9 /usr/local/lib/perl5/site_perl . # rrdtool -V RRDtool 1.3.6 Copyright 1997-2008 by Tobias Oetiker <t...@oetiker.ch> Compiled Feb 6 2009 09:28:18 Usage: rrdtool [options] command command_options Valid commands: create, update, updatev, graph, graphv, dump, restore, last, lastupdate, first, info, fetch, tune, resize, xport RRDtool is distributed under the Terms of the GNU General Public License Version 2.
