It is:

Program received signal SIGSEGV, Segmentation fault.
0x4014cf7e in vfprintf () from /lib/libc.so.6

This is caused by this line syslog line in nnrpd/misc.c

    /* Skip first two fields. */
    if ((p = strchr(buff, '\t')) == NULL) {
        syslog(L_ERROR, "%s bad_history at %ld for %s in BLANK", ClientHost, offset, HashToText(*key));
        return NULL;
    }

Apprantly this routine thinks the history is corrupt? I have rebuild the history
by contrib/fixhist, but this didn't find any errors.

I don't think the history is really corrupt. I do have a large history:

-rw-r--r--    1 news     news     5861595934 Oct  9 14:48 /usr/local/news/spool/db/history
-rw-r--r--    1 news     news           50 Oct  9 14:48 /usr/local/news/spool/db/history.dir
-rw-r--r--    1 news     news     1043413200 Oct  9 14:24 /usr/local/news/spool/db/history.hash
-rw-r--r--    1 news     news     1391217600 Oct  9 14:48 /usr/local/news/spool/db/history.index

The server holds lots of non-bin articles.

What's going on?

Thanks.
