Describe your problem

While parsing a simple text document, the process got stuck at 8.41% completion. Upon reviewing the ERROR.log, I noticed the following errors:

Questions

1. Why is the process unable to acquire the update_progress lock?
2. How can I resolve this issue and allow the progress to continue?

I don't think this is the reason to stuck. What the status of your machine, like CPU and RAM usage? And is there any progress consuming CPU a alot ? What's the log message when you hover to the process bar?

While parsing a simple PDF document，the process got stuck. Upon reviewing the ERROR.log, I noticed the following errors（web anylysis state is failed）: 2024-11-11 19:03:30,675 ERROR (3359414) set_progress:(87a71deca01c11ef8571189ba584b5f6), failed to acquire lock update_progress 2024-11-11 19:03:30,741 ERROR (51478) set_progress:(87a71deca01c11ef8571189ba584b5f6), failed to acquire lock update_progress 2024-11-11 19:03:34,152 ERROR (49784) set_progress:(87a71cc0a01c11ef8571189ba584b5f6), failed to acquire lock update_progress

I don't think this error would cause stucking issue.
