Memory usage doubles on reload

Hello we are running nginx 1.2.7 with this in conf:
  output_buffers 5 5m;
  sendfile off;

That works well, BUT if I reload server configuration with nginx -s reload
Memory consumptions for few hours(clients use long lived(few hours) tcp
connections). Is this behavior correct? Can we avoid this? We have to had as
twice much RAM to be able to restart nginx under load.

Sincerely Petr Holik
