Description Kari Takanen 2012-04-05 07:42:18 UTC
The program MJ12node (http://www.majestic12.co.uk) crashes randomly with current Mono git version and sgen. This didn't happen with the earlier git version I used which was probably a month or two old.

I've attached some gdb output.

Mono version used:

Mono JIT compiler version 2.11 (master/5091f77 Thu Apr  5 10:16:49 EEST 2012)

        TLS:           __thread
        SIGSEGV:       altstack
        Notifications: epoll
        Architecture:  x86
        Disabled:      none
        Misc:          softdebug
        LLVM:          supported, not enabled.
        GC:            sgen


OS: Ubuntu server 12.04 64-bit

Please let me know if you need more info or debug data.

I can provide access to the server where this software runs, if it helps.

I'm trying to reproduce this, but I can't get the crawler to work.  I register, but it always complains I'm not registered:

[9/7/2012 10:15:12 AM] Failed to receive more URLs, response code: NotRegistered

Also, test login always works, no matter what the password is (it does required that the email address was registered previously).
Comment 5 Kari Takanen 2012-09-15 06:30:38 UTC
It should work after saving login details and restarting the software.

However this bug can be closed, I haven't seen it happening recently. I hope that you would take a look at https://bugzilla.novell.com/show_bug.cgi?id=669519 as it is still an issue.
