APAR status

  • Closed as program error.

Error description

  • On Linux platform with KAIO, any read and write failure can go
unnoticeable by Informix. The IO failure will not reflect in the
online.log and Informix will not bring chunks off-line, which
could lead to data corruption and other problems.

Local fix

  • This can be observed only with KAIO enabled. If you turn off
KAIO it might provide a temporary solution, but this can have
unwanted effects on the I/O performance.
