@GiedriusS Sure, I will try to implement a test which simulates store errors. it should be running into the deadlock with the original code, but not with the patch. I hopefully can have something by the end of the week. |

Worker threads no longer exit on error, instead they collect them into a multiError and keep working.
Fix proposal for #7514
Changes
Changed concurrent worker behavior in case of error in Exists call, they no longer exit on error, instead collect errors in a multiError and continue working.
Verification
I plan to force errors using minio and try to exhaust the threadpool, but I am not yet sure how exactly. Without the patch I should be able to do that, with the patch it should not be possible.
