We have Informix IDS 7.30 running under SCO 5.0.5. Backups by ontape fail with an error: "I/O read chunk 90, pagenum 2, pagecnt 1 --> errno = 9"
But when we are doing normal queries, it's all fine. Any ideas?
First, I'd run oncheck against the reserved pages and system pages to see if anything's getting reported here. Find out what your OS's Error 9 means. The error number most probably comes from the OS, and this may tell you what's happening.
