求助：Bad Page

visorqw

请问informix本身会自动调用SQL执行查询系统表的信息吗？
下面是online.log下的，DB突然出现Page Check Error,然后重启后又发现chunk down.
Bad Page应该出现在是系统表，理由是在af.5e3987ec文件中查找到SQL:
Current SQL statement :
  select count(unique tabname) from systabnames t, sysptnhdr p where
    t.partnum=p.partnum and p.nextsiz > (select MAX(leng) * 2.00 from
    syschfree f, syschktab c, sysdbspaces d where f.chknum=c.chknum and
    c.dbsnum=d.dbsnum and d.name=DBINFO('DBSPACE',p.partnum))

online.log:

确信是DB自己调用的?~?

按照所说的用oncheck -ce检查一下有没有块重叠。

由于是生产环境，目前还不能oncheck -ce.
不确认是不是DB自己调用的，但是能看到这个SQL owner是informix
