From: "Kollár László" Date: 2009-08-13T18:36:19+09:00 Subject: class(es) become NIL .. how? Hi, I've written a mail gateway in ruby. It is in the log-run (stress)test phase. I've encounter the following weird phenomen: The daemon suddenly forgot one of its class that is rather the class became to NIL. Soon after the daemon silently exit and died. I cannot settle whether is it my program's fault or Ruby's fault or The Sequel's fault (Because the class that became to NIL is a Sequel::Model class). How can debug or trace a problem like this? How can define the source of the problem (program, ruby,sequel)? Any advice are welcome Thank you Laszlo
