--- Comment #1 from Howard Chu <[email protected]> --- (In reply to [email protected] from comment #0) > I have 2 python scripts writing to a database (lmdb 0.9.26, py-lmdb 0.98) > and 5-10 lua processes (with lightningmdb module which uses lmdb 0.9.22) > which are long-running serving queries from the database. > > The database seems fine, not corrupted, and the python writes still working > all the time. But periodically (perhaps 10-20% of the time), in a way I am > unable to reliably reproduce, when the lua starts up every time a query is > issued txn dbi_open returns "MDB_BAD_TXN: Transaction must abort, has a > child, or is invalid". A direct restart of the processes does not fix this > issue, however stopping lua+python and then starting again after a 5-20s > wait usually fixes the issue. This has been reproduced over multiple servers > but I'm at a loss as to how to debug this any further? You didn't specify what OS you're using. This doesn't sound like an "all hardware/systems" type of issue. You should probably not mix versions, as a general rule. -- You are receiving this mail because: You are on the CC list for the issue.
