Segfault on startup after upgrade

After upgrading to 3.13.0.3 from 3.7.4.1

Jul 03 2017 14:13:58 GMT: FAILED ASSERTION (proto): (transaction.c:415) unexpected transaction origin 0
Jul 03 2017 14:13:58 GMT: WARNING (as): (signal.c:210) SIGUSR1 received, aborting Aerospike Community Edition build 3.13.0.3 os debian8

Any ideas ?

Could you provide the stack trace that followed this exception?

Sure,

We have tried several versions above 3.7.4.* (3.9, 3.10, 3.13) and reproduced every time. This happens every time just before hitting the 2% migrations complete after startup.

Thanks,

Could you share your server config?

Also would you be able to accept a dev build to help pinpoint how this transaction reached the transaction queue?

Above the config file. I will come back to you on monday, after negaciating with our production engineers to test your dev build.

Thanks,

I suspect this is LDT related. Other paths are easy to rule out since they quickly set the transaction origin. However, LDTs make use of having it set to 0 for a while. I wasn’t able to find how it could reach a transaction queue while in this state though. The dev build should cast a spotlight on where the issue arises. Could try to reproduce outside of production if you are able to test your LDT load against it. You could even start with a single node cluster, but it may need more than one node to reproduce.

Also be aware that LDTs have been marked as deprecated for some time now, if your app still relies on them know that 3.14.1.1 will be the final release to support them.

We were able to test your dev version, stack trace above

Well seeing as it happened immediately after an LDT record failure, my bet is definitely on LDT. You should get off LDT ASAP, as Aerospike is no longer continuing to offer that capability in future versions due to many issues with LDT
