Summary The command "itadmin variable show" may return a variable not found error if an attempt is made to read a configuration variable while another thread is writing the variable.
Article Number 28565
Environment Orbix 6.x All Supported Platforms
Question/Problem Description In a multithreaded environment it is possible that the command "itadmin variable show"  may return a variable not found error if an attempt is made to read a configuration variable while another thread is writing the variable.

Clarifying Information This can only happen in an extreme edge case and most likely where a variable is being updated regularly.
Error Message variable <> not found.
Defect/Enhancement Number
Cause
Resolution
Workaround Catching such an error and retying the operation once will solve this issue.
Notes The CFR  is used to hold system configuration and will not be frequently updated in most systems. This error is only associated with a read call and should not cause any major issues and will work once a retry is in place.
