Informix version 5.03 chunk read error

Dear Informix DBA/Specialists, Has anyone exprienced this errors before on Informix version 5.03.UC1 On-Line running on a Sequent platform. In need some help in diagnosing what is the cause of this problem. Raw disks are being used by Informix here under SVM control and the permission and access rights are fine. "09:18 I/O read() chunk 20, pagenum 60881, pagecnt 4 ---> errno = 1" "09:21:04 I/O write() chunk 45, pagenum 29295, pagecnt 1 --> errno = 4" ( repeated many times ) "09:44 I/O read() chunk 45, pagenum 4 pagecnt 1 ---> errno = 2" I have written my comments based on the Unix system call point of view. Please give your comments on this errors from the Informix prespective. >"09:21:04 I/O write() chunk 45, pagenum 29295, pagecnt 1 --> errno = 4" Errno 4 refers to 1 EINTR "Interuppted system call" which is explained in manpages intro(2) as 'an aynchronous signal (such as interrupt or quit) which the user has elected to catch, occured during a system call. If the execution is resumed after processing the signal, it will appear as if the interrupted system call returned this error condition.' >"09:18 I/O read() chunk 20, pagenum 60881, pagecnt 4 ---> errno = 1" As for the errno 1 that occured per manpage it refers to 1 EPERM "Operation not permitted" >09:44 I/O read() chunk 45, pagenum 4 pagecnt 1 ---> errno = 2" while errno 2 means ENOENT "No such file or directory".
