关于sphinx大数据?报错

@张小农 你好，想跟你请教个问题：

最近在学习sphinx，遇到了一些问题，刚看到你发的文章《sphinx+mysql+php 秒杀大数据》http://my.oschina.net/rookier/blog/406140?p=1， 相信你能帮助我解决问题；

我现在有个数据表<log_merger>，里面有将近2亿条数据（根据时间的推移可能会更多），和你的55G大数据还相差甚远，但是表中有14个字段，恰好这14个字段在后期都有可能作为查询条件，下面是属性：

sql_attr_uint = logId
sql_attr_uint = outId
sql_attr_uint = matId
sql_attr_uint = memId
sql_attr_uint = worId
sql_attr_string = adId
sql_attr_string = temId
sql_attr_string = extId
sql_attr_uint = plat
sql_attr_uint = type
sql_attr_uint = draId
sql_attr_uint = proId
sql_attr_timestamp = cTime
sql_attr_string = reqIp

source config{
    type            = mysql
    sql_host        = localhost
    sql_user        = root
    sql_pass        = xxxxx
    sql_db          = db_log
    sql_port        = 3306
    sql_query_pre = SET NAMES utf8

    sql_query_pre = SET SESSION query_cache_type=OFF

    sql_ranged_throttle = 100

    sql_attr_uint = logId
    sql_attr_uint = outId
    sql_attr_uint = matId
    sql_attr_uint = memId
    sql_attr_uint = worId
    sql_attr_string = adId
    sql_attr_string = temId
    sql_attr_string = extId
    sql_attr_uint = plat
    sql_attr_uint = type
    sql_attr_uint = draId
    sql_attr_uint = proId
    sql_attr_timestamp = cTime
    sql_attr_string = reqIp
}

source data : config{
    sql_query = SELECT logId,outId,draId,proId,matId,memId,worId,adId,temId,extId,plat,reqIp,type,UNIX_TIMESTAMP(LEFT(cTime,10)) as cTime FROM `log_merger`
}
