my method of error finding:
1. run by hand from server and with log (error in log: data problems, connections problems)
2 run by hand task
3 run by hand from SSIS
4 run all SSIS by hand
Not find reason ?
Error possible due to count of parallel proccess of QVB simultaneously running- In SSIS change how many tasks can run simultaniously.
Thanks for getting back to me.
I believe this issue might have been a rare occurrence as it has not resurfaced for the last 4 days.
I do believe it is somehow related to an issue with SSIS and the QlikView reload engine where mutual exclusion can occur where 2 SSIS tasks can call a QlikView Reload engine at exactly the same time.
This usually ends with 1 of the task failing but the above can occur as well if the CPU is under high duress.
Please let me know what you think?
Thanks very much.
Although I do not know why this issue occurs. I did discover code for the C# EDX execution application that will abort the Task exceed the specified Timeout.
An If condition stating the timeout paramentar
_timeout = 3600; /* 60 minutes For Raw Layer */
Qlikview C# API command to abort the executiong task.
If you have any quereis please let me know.
