Patch level detected:Dollar Universe 6.4.01
Product Version: Dollar.Universe 6.4.01

Description :If task recalculation is forced, for example when exclusions are removed on all tasks, and if there is a task which uses daily dependent windows, the calculator blocks on this task when it recalculates launches for all tasks. Tasks that comes after such a task, will not have their launches recalculated again.

High CPU load is linked with this kind of task. The uxioserv process uses 100% of CPU in Linux.

DUAS has to be stopped with unistop force.
To be able to update this task, DUAS has to be launched without starting CAL and LAN, otherwise CAL will block again the data entry of this task in the u_fmta60 dataset.


Cause type:
Root Cause: The calculator freezed because of an incorrect lock handling on the task data file.
