IO bad request chunk 4

27-Dec-1994 Subject: I/O bad request chunk 4, pagenum 108, pagecnt 1 --------------------------------------------------------- The 27. December is a bad day to get problems - I could not get any help from Tech. Support, so I try this newsgroup. I get "I/O bad request chunk 4" in my OnLine log file and from tbcheck -cr. Chunk 4 is my physical log. The OnLine is running OK, but I get this I/O error and want to avoid it. How can I remove this problem ?
