求助502错误，谢谢
服务器配置是独立服务器，16G内存LNMP是基于最新的1.1版本安装，有升级过PHP
PHP：5.5.15
MYSQL：5.5
系统：debian7 x64
程序用的是帝国CMS，502出现是在批量生成(目前数据量不大，单个生成都可以成功)内容页时，部分表(同时刷新8个表，有3-4个502)会出现502导致刷新不成功。
按置顶网里挨个排查了下，问题没有解决。
我帖上php-fpm日志，麻烦帮忙看下，感谢！！
上面的日志就是出现502时的记录，大概类似于： WARNING: child 39267 exited on signal 7 (SIGBUS) after 4.396186 seconds from start

NOTICE: child 39438 started目前8个表的数据还没有2000条，但生成内容页时会有大量的sql查询，现在有些怀疑是mysql的问题，但按军哥的教程重新设置了mysql的参数，问题依旧。
求帮忙看看，谢谢啦！
目前的php-fpm.conf，这个是出502问题后改，目前流量不大，内存剩余好多，所以我设置成static了。
listen = /tmp/php-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = static
pm.max_children = 100
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 6
#pm.max_requests = 1000
rlimit_files = 30000
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log
[ 本帖最后由 uk8u8 于 2014-8-13 14:18 编辑 ] php-fpm日志里只有运行超时的，你把https://bbs.vpser.net/thread-1144-1-1.html 第四条改过了吗
