Re: [GNC] Huge number of missing transactions
I very much appreciate the comments but to confirm, this definitely was not a simultaneous user issue. There are just two of us, the lock message is pretty clear and because of our schedules, there is also rare overlap for when we might both even need to access the files. That said, I still hope and presume it was somehow operator error in some way though beyond the already discussed idea of accessing the same data file repeatedly from very different versions, I cannot begin to guess how it would even be possible to delete such a number of unrelated transactions. As for recovery, what I did was indeed go back just a few days, basically a day before the data loss. The amount of work lost was minimal, especially as I was able to export most of the transactions that had been entered after the data loss and then import them into the older file. Really, recovery and getting back to ground zero was not a big deal.

I will second that. Gnucash does NOT support multiple simultaneous users. It does support multiple sequential users but if used that way the message "could not obtain lock" has to be treated very seriously. A single user can override this and proceed anyway, but if there is ANY chance a different user is accessing the data cannot do that. For a program to support multiple simultaneous users it must be running UNDER the control of a DBM (database manager) program. In which case the simultaneous users might not even be using the same program to access the database (as long as all such programs are running under the control of the DBM). Back in my working days maintained apps running under DB2 (a DBM for mainframe SQL). So in a case like this, multiple users and the data on a network drive, that is overwhelmingly likely the problem. Unless you can definitely rule out simultaneous access issues, look no farther. No point in trying to analyze the details of what happened to the data because the consequences of simultaneous access are unpredictable.

Re: [GNC] Huge number of missing transactions
Sadly, no.. those help docs are pretty basic - I have looked at most of what can be found in the various docs and generally searching. I'll probably need to go to the code repository and look for comments or something along those lines. Still would be good to at least confirm that our actions of accessing the data file with two app versions was the issue. It was a pretty devastating number of transactions. Thanks!
