Why not calling txn_loglvl() instead of DBGMDB_LEVEL_MDBAPI?
There was a problem hiding this comment.
txn_log() is used only for txn related function It allows to log when txn are open and closed when
DBGMDB_LEVEL_MDBAPI or DBGMDB_LEVEL_TXN is set but log txn backtrace only if DBGMDB_LEVEL_TXN is set

A better fix than PR 6349 about corrupted vlv cache Problem is a race condition because txn was released while building the cache. Solution keep the write txn open until the cache is fully rebuilt. Also fixed some debug logs And also added the source of a tool useful to check the vlv cache consistency Note: this remove PR #6349 and integrate PR #6356 Issue: #6347 Reviewed by @tbodaz (Thanks!) (cherry picked from commit 8366819)
