Hi, I am trying to upgrade OTRS. I am running the new installation in the same machine that I have the current installation which I am running with mod_perl. So I disabled mod_perl for the new installation. I get this error when I try to test it: Bad address at /otrsnew/bin/cgi-bin/../../Kernel/System/Log.pm line 230. my $String = ''; if ( $Self->{IPC} ) { Line 230:-> shmread( $Self->{Key}, $String, 0, $Self->{IPCSize} ) || die "$!"; } Here's what I get for ipcs -m ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 491520 gdm 600 196608 2 dest 0x02a622c7 65537 root 777 1 0 0x02a622c6 98306 root 777 4096 0 0x02a6232a 524291 apache 777 1 0 any idea? --sharif
