> Key: TRAFODION-2653
> URL: https://issues.apache.org/jira/browse/TRAFODION-2653
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-exe
> Affects Versions: 2.2-incubating
> Reporter: Selvaganesan Govindarajan
> Assignee: Selvaganesan Govindarajan
>
> This issue was observed in Esgyn internal testing. When the system is heavily
> loaded, the scratch IOs can return EAGAIN that translates to
> OPERATION_NOT_COMPLETE in Sort scratch IO handling. This condition is not
> being handled correctly.
> Scratch IO doesn't use asynchronous IOs though the scratch file is opened in
> non-blocking mode. EAGAIN is returned from these IO operations very rarely.
> It should be fine to open the scratch file in blocking mode to avoid this
> problem
