I know check_selenium by itself will throw a "CRITICAL" if it finds the word "ERROR" anywhere in the test case's output, though I believe the RC server will re-try the test if it can't establish a session ID on the first attempt in many cases. So the first session on these tests might be failing, but a second/third may be succeeding. The logic in check_selenium i'm referring to:

Code: Select all

my $output = `perl $script 2>&1`;
if ( $output =~ m/(ERROR.+\n)/ ) {
    $message = $1;
    $rc = 2; #end it with an error
} elsif ( $output =~ m/OK/ )  {
    my @lines = split(/\n/, $output);
    foreach my $line (@lines) {
        if ( $line =~ m/OK:/ ) {
            ($message, $rc, $performance_msg, $items_ran) = split(/\|/, $line);
            $message = "$message | $performance_msg\n";
        }
    }
} else {
    $message = "UNKNOWN: $output";
    $rc = 3;
}

You might try altering this script to set $message equal to $output like so to get better debug information:

Code: Select all

$message = $output;

Though this could cause issues with the status output overflowing as @avandemore pointed out.

mcapra wrote:You could try adding a separate regex match to check_selenium for Jetty (the web server component used by the RC server) server exceptions:

Code: Select all

my $output = `perl $script 2>&1`;
if ( $output =~ m/(ERROR Server Exception.+\n)/ ) {
    $message = $1;
    $rc = 3; #end it with an unknown
}
elsif ( $output =~ m/(ERROR.+\n)/ ) {
    $message = $1;
    $rc = 2; #end it with an error
} elsif ( $output =~ m/OK/ )  {
    my @lines = split(/\n/, $output);
    foreach my $line (@lines) {
        if ( $line =~ m/OK:/ ) {
            ($message, $rc, $performance_msg, $items_ran) = split(/\|/, $line);
            $message = "$message | $performance_msg\n";
        }
    }
} else {
    $message = "UNKNOWN: $output";
    $rc = 3;
}

Though the call stack you sent a screenshot of is incomplete. I'd need to see the whole thing to be able to say why Jetty is crashing.
