I/O error message

[dapenDaniel]

Hi,

I am running SAS on a supercomputer (Linux system) and an error message was shown in the log file.

ERROR: An I/O error has occurred on file WORK.CC.DATA.
ERROR: UNIX errno = 122

I searched this error message and most of the UNIX errno = 24 rather than 122. What is the difference? 

The number of observations is 10,000. I tried to decrease it to 5,000 and even 2,5000 but it did not work. How can I fix this issue? Thanks.

I believe it indicates the number of datasets that are allowed to be open, please check the link below.

increase the limit to the number of files that the operating system allows to have open at the same time.

But I do not know how we can increase that limit. You might need to go though the link.

See here: https://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html

#define EDQUOT          122     /* Quota exceeded */

The server administrator has diligently set quotas in WORK, so one user can't wreck the day for everybody else.

Clean up your WORK before running this step.

PS the above link is the third result of a Google search for "UNIX errno = 122". See Maxim 6.
