Re-occurring error "cannot register synch handler in current tx"

[René_]

We have the problem that in our Nuxeo installation an error that affects the whole installation occurs from time to time. Up to now I could not determine a pattern when exactly it is occurring. We are using CMIS to access Nuxeo from other applications, but the error does not occur exactly when we do this. Any help appriciated. You can find the full jstack and server error log on dropbox. The most important part of the exception can be found below. https://www.dropbox.com/sh/xrm2h1hn49xgw2h/AACUo22t09T8Q8Mhk4AKAFZla?dl=0

Seems as though it's happening because your transaction request is timing out for some reason, thus marking it to roll back. This happens because pushing the transaction further would prove useless, since the transaction has expired.

Also you haven't stated what Nuxeo version you're using, nor provided the full stack trace including the "caused by".

As written above the full stack trace can be found on Dropbox including the jstack result. The version can be found in the meta data of the post. I didn't know I have to be redundant. It is 7.10 HF13.

Ah sorry I read too quickly. Also you should use the Comment field and not Answer if you just comment.

I'm aware of that but the mobile version of quandary has no comment button. I just found out that I need to ask for the desktop version of the page to comment
