Post by pkll »

Hi All,

I am getting below error.
APT_IOPort::readBlkVirt: read for block header,partition 0,[fd,5], returned-1 with error 10,054(Unknown error).
When I executing job with single node I am not getting any error or warning messages.But, when I am executing four nodes I am getting above fatal error.But all records are processing output file with green color.

Could you please let me know how to resolve this ?

Thanks in Advanced Help!!!

Although you did not pioneer in getting this error but seems you do not have much info available on this error.

Do you always get this error when you run on multiple node. Did you try looking at resources on the server when this job is running? do you have some other program writing to same dataset? Try running your your job in isolation and monitor disk during that time.

Involve your official support provider, especially for errors of the "unknown" type.

Well, you know that it works for one, but not for more. That is a start.

Look at your APT file. Look to see if you have read/write permissions to your scratch and resource disks for the other nodes.

Look at your input file to the job. Is it a dataset? How many partitions was it created with?

Is it sequential? What partitioning method did you define in your other stages? (hash, all, same, etc...)

We faced the same error recently. Upon analysis, we couldn't find anything concrete so a PMR was raised with IBM. IBM confirmed that the issue is related to Operating System(windows). As of now we are still awaiting their further response and resolution.

For reference, below is the error we were getting.

Lookup_264,0: APT_IOPort::readBlkVirt: read for block header, partition 0, [fd 14], returned -1 with errno 10,054 (Unknown error)

Regards!
