Hi, Thanks for the report and the reproducer. I reproduced it on 2.18.0 with your project, and on master with a small test: an interrupted ATOMIC put of a new Externalizable class calls the failure handler with "B+Tree is corrupted".
I created a ticket: https://issues.apache.org/jira/browse/IGNITE-29241 The test is in a draft PR: https://github.com/apache/ignite/pull/13779 If a committer agrees with the issue, I'm happy to fix it.
