Marcus Christie commented on AIRAVATA-3372:
-------------------------------------------

The large number of task statuses were caused by Helix bug. Dimuthu said:

 this is due to the same bug in helix core where tasks are periodically getting 
executed in very rare cases. However we have a soft check done in the 
implementation to skip any job submission. I'm going to cleanup the status in 
db and upgrade the helix version to 0.8.2 -> 0.9.7 in dev to initiate the 
upgrade process.

After the clean up I'm seeing better performance (not timing out any longer), 
but it is still slow so I'll keep this issue open to investigate if there is 
anything we still need to do at the database level to fix the performance.
