Could not start BerkeleyJE transaction
Hey I've just encounter this issue and needed to restart the entire server for it to go away.
I believe it's the issue being described here

I can see that a fix has already been proposal for this: https://github.com/JanusGraph/janusgraph/pull/3990
Is there a rough estimate of when this will be available for release? we've only encountered the issue once but it is quite serious. Thank you
Which version of JanusGraph are you using?
Because this was released as part of 1.0.0
hmm I'm using version 1.0.0
I think the fix was merged but then later reverted though
@Boxuan Li is involved in that PR so he probably has better context š«”
@Florian Hockmann As @tien mentioned, I had to revert that PR due to failure of tp-tests
The author, Pavel, never reopened a PR to fix the test
@tien would you be interested to take this forward?
My knowledge over this is extremely limited, so I wouldn't be so comfortable touching something this critical & low level tbh :))
But can take a look of course to see what is involved
Ah, I see, I was too quick with my reply and didn't scroll down in the PR to see the revert
@tien the workaround is you apply that fix to your own fork
For that PR how can I reopen it n have this "tp-test" thing trigger for it?
You cannot reopen it because it's already merged. You could cherry-pick that commit again (or revert the revert), and add
[tp-tests] to the commit message and PR title.I have cherry picked the commit from that PR to a new one here https://github.com/JanusGraph/janusgraph/pull/4413
Hey so I've created a much more simplified version here instead: https://github.com/JanusGraph/janusgraph/pull/4425
I think this shouldn't mess with any of the existing tests
Hopefully you guys can assist me in getting this fixed soon, got a heart attack from the second time this had happened for our DB today lol.
Again my knowledge over this is very limited so would appreciate any guidance :p
The approach of that PR is to simply close the environment whenever there is an interruption happen. And that each beginTransaction will try to reopen the env if it's closed.
I think I've figured it out, can you guys help me check the changes?

š@Boxuan Li @Florian Hockmann
I could do rubber stamping but I would like to see if anyone else could review. I know very little about BerkeleyDB.
@Boxuan Li There's this CI step that seem to randomly failed to upload the test artifact, can you retry that for me?

Sorry for the spammy changes & CI test btw š
Okay I've got all tests to pass
Anyway this fix can be available in a patch version?
Anyway this fix can be available in a patch versionYes
Awesome, would definitely help me sleep sounder at night with this fix haha
