extent analysis

TL;DR

The issue might be resolved by adjusting the stream idle timeout settings to prevent premature timeouts and allow Ultraplan to auto-recover and continue planning.

Guidance

  • Investigate the current stream idle timeout configuration to determine if it's set too low, causing the "Stream idle timeout - partial response received" error.
  • Consider increasing the stream idle timeout value to give Ultraplan more time to receive a complete response and auto-recover.
  • Review the Ultraplan documentation to see if there are any recommendations for optimal stream idle timeout settings for the specific use case.
  • If possible, test Ultraplan with a longer stream idle timeout to verify if it resolves the issue.

Notes

The provided error message suggests a timeout issue, but without more detailed logs or configuration information, it's difficult to provide a more specific solution. The Errors section is empty, which might indicate that the issue is not being properly logged or reported.

Recommendation

Apply workaround: Increase the stream idle timeout value to a higher setting to allow Ultraplan to auto-recover and continue planning, as this is likely to mitigate the "Stream idle timeout - partial response received" error.
