全新安装的smth 1.2.1，新建帐号后登陆，新建讨论区A，发文章，到这儿都正常，
然后再到这个讨论区A发文章，就会掉线，如果在重新开一个讨论区B，发文章
正常，但是发第二篇文章就不正常了，由于对Solaris不是特别熟悉，调试也不是
很熟悉，-_-,请问这可能是由于什么原因引起的？

经过跟踪发现在发表文章的时候,after_post函数里面调用get_nextid
然后bcache_lock，执行到getboardnum函数的时候就出错了，

int getboardnum(const char *bname, struct boardheader *bh)
{                               /* board name --> board No. & not check level */
    register int i;

    for (i = 0; i < brdshm->numboards; i++)
        if (!strncasecmp(bname, bcache[i].filename, STRLEN)) {
            if (bh)
                *bh = bcache[i];
            return i + 1;
        }
    return 0;
}

在进入循环的时候退出的，而在其它情况下调用这个函数暂时还没发现推出的现象，
我在前面的一篇文章中也看到有人说在Sparc机器上面执行到这一步就会推出的现象
这篇文章是

跟上面BTang3文章的bt一样，而且她说的开新班掉线的问题也有

按照这样patch以后，采用
./configure --prefix=/bbs --enable-site=fb2k-v2 --without-mysql  CFLAGS= -g  --disable-www
这样的方式去编译安装，则没有问题，如果在configure的时候添加了mysql,ssl,ssh或者www等发文章就又和原来一样掉线了，出错的地方也一样
