Re: possible issue in mod_perl 2.0.4 with respect to STDERR
[In reply to]

No its not VHOST
The configuration in httpd look like this
<Perl>
my $app_home = $ENV{APPS_HOME};
my $config = ConfigLoader::include("$app_home/conf/
ursforms.pl");
my $clog = '"| rotatelogs '. $config->{log_accessfile} .
'%y%m%d 1M " common';
my $elog = '"| rotatelogs '. $config->{log_file} . '%y%m%d
1M "';
$ServerAdmin = $config->{contact};
$ServerRoot = $app_home;
$DocumentRoot = $app_home . "/webdocs";
$ErrorLog = $elog ;
$CustomLog = $clog;
$PidFile = $config->{log_pidfile};
$LockFile = $config->{log_lockfile};
$ScoreBoardFile = $config->{log_statusfile};
</Perl>
Where the $config->{log_file} is
/nfs/private/user/sns/log/ursforms.myserver-44088.log
% ps -ef | grep ursforms | grep sns
