Hello @Gaurav2 

After Oracle July patch, the task gets crashed. The R&D identified the issue and provided the Test patch to resolve the issue. I would request you to please open a support ticket with us.

Hi Suresh,

We have already opened the case 00299298. Waiting for the reply.

In the meantime, the issue identified by R&D team have same error "Process crashed with signal 11, backtrace: !"

Just to mention, we applied July patch on 3 Source DB's. Each DB have 2 source LSS task.

Means total Oracle Source tasks are 6.

Out of 6, only 2 are failing with the error mentioned above.

Hi All,

Do you have any update about this post?

I got an error this week on Qlik servers with release 2023.11.0.468, tasks crashed without any error messages.
So, after many tests, I decided to upgrade the Qlik to release May 2024, and then I started to see the error "]E:  Process crashed with signal 11" before the task failures.

The patch "Database Release Update : 19.24.0.0.240716" was applied in our source database before start to have this issue. I already have an opened case for my issue, waiting for the reply.

Regards, 
George

Hello @Gaurav2 ,

Please have a look at Qlik Replicate tasks crash due to changes to the redo log format after installing Oracle July 2024 patch on Oracle 19.

Hope this helps.

John.
