Do you get any more details when you start the wrapper with –d ?

  Hi Guys,

  After two weeks successful running several authentication in my development environment with average 10-20 users, i encourage myself to put in my production. it was up and ran with +-1000 users but only took 3-5 hours then squid suddenly stopped with error:
