smthbbs 1.2.1 stable
Redhat 7.3

最近出了一些莫名其妙的问题
开始某个版面浏览的时候立刻断线，但是该版面文件属主都是bbs，并没有什么问题啊？
检查发现 浏览到某一个屏幕的时候短线的，具体为2XX-2XX帖子
用web方式进去将那一屏幕的帖子删除后，可以进去了
不过按.进回收站也会掉线，只好把回收站文件给删除掉了

这次又发现一个版面问题更大,从上翻到 1380 帖子就掉线
而从上往下翻到1220号帖子也掉线了
感觉很奇怪，这些文章以前就有，没有问题啊？

最近因为系统升级内核失败，重装了系统和重新安装了bbs了！
也不清楚问题在哪里

记得以前版面上有讨论过卡住十大的时候 如何gdb
不过我抓不住那个断线的时候，一掉线，那个就没了
而在线的时候attach，又动不了了，这个是我在线的时候attach的，那个掉线的一刹那抓不住
