    Program received signal SIGPIPE, Broken pipe.

    SIGPIPE is not a "segfault". It is completely normal for a socket app to receives SIGPIPE signals upon socket disconnections. See this for details on how to handle SIGPIPE when using GDB: http://wiki.synchro.net/howto:gdb#handling_sigpipe

    Did you build with DEBUG=1 and running a debug version?

    I've not had any sort of segfaults with antispam. Are you using anything different than the defaults?

    That's the second report of a recent crash (segfault) in sockreadline() in mailsrvr.c. Looking at the code and the recent changes, I see no obvious cause. If it happens again, a backtrace from a debug build would be more helpful. The log output from around the time of the crash (like you provided) is also potentially helpful.

    That's the second report of a recent crash (segfault) in sockreadline() in mailsrvr.c. Looking at the code and the recent changes, I see no obvious cause.
    If it happens again, a backtrace from a debug build would be more helpful. The
    log output from around the time of the crash (like you provided) is also potentially helpful.

    Since I recompiled after you fixed the users.dat open files issue, I've not had a
    crash. My board reports as being up for 25 hours which is pretty unusual. It's only
    been lasting maybe upto 12-15, certainly not over 24. It might be coincidental or
    it could be the fix. Though I don't see why that'd have anything to do with the sockreadline function?
