Not Newest Record Error

[devmanhinton]

When adding an edge got:

"<NativeException: com.orientechnologies.orient.core.exception.OConcurrentModificationException: Cannot ? the record #7:0 because the version is not the latest. Probably you are ing an old record or it has been modified by another user (db=v26 your=v0)>"

Fix was to rescue the error and then retry. (This worked). Don't know if there is a better workaround or exactly what is causing this? ... Thanks!

[lvca]

Can you send us the full stack exception please?

[devmanhinton]

Fix actually did not work, removing debugging logging changed concurrency -> same problem.

Updated to most recent, stable release locally to test (1.4.1.) Led to same result.

Full stack trace: (From rescue exception Object in Ruby) Note we are using Pacer/Blueprint

I don't know how did you manage the transaction, but are you aware OrientDB has an optimistic transaction model? https://github.com/orientechnologies/orientdb/wiki/Transactions#optimistic-transaction. So you've to retry if a concurrency problem occurs. Have you done it?

No answer for a while: I'm closing this issue. In case comment it to reopen it again.
