I updated to PHP 7 at my localhost, but since then anytime i want to redirect from one page to another in my nette application, I'll receive error: 500 - Internal Server Error.

I was searching through stack overflow and found a problem that is quite similar to mine here: How to solve "mod_fastcgi.c.2566 unexpected end-of-file (perhaps the fastcgi process died)" when calling .php that takes long time to execute? . However, I don't work with large files and my connection dies immediately.

My /var/log/lighttpd/error.log

Update 7.3.2016

I switched from php fast cgi to php-fpm and interesting thing is that problem prevails, but is less often. Sometimes the redirect jump to 500 and sometimes not. And error log again:

I've finally found a solution. It is probably Nette / Cassandra related problem.

The error was appearing because of object Nette\Security\Identity, after I assigned user data into it:

public function authenticate(array $credentials) {

  // Retrieve username and password
  list($email, $passwd) = $credentials;

  // Select user with given email from database
  $usr = $this->daoManager->getDao("AppUser")->loadByEmail($email);
  if ($usr == null || count($usr) == 0) {
    $msg = 'The email is incorrect.';
    $arg = self::IDENTITY_NOT_FOUND;
    throw new Nette\Security\AuthenticationException($msg, $arg);
  }

  // TODO Check user password
  // TODO Check verification      

  // Create identity - THE PROBLEM WAS HERE
  return new Identity($email, $usr['role'], $usr);
}

It was caused by value 'registered' in $usr array which was of type Cassandra\Timestamp. Since then almost every redirect crashed with above mentioned error.

Following code fixed the issue:

return new Identity($email, $usr['role'], $this->fixUserArray($usr));

Where:

protected function fixUserArray(array $user) {
  $result = array();
  foreach ($user as $key => $val) {
    if ($key === "registered") {
      $result[$key] = $val->time();
    } else {
      $result[$key] = $val;
    }
  } 
  return $result;
}
