Hi,

Looks like transaction manager crashed for some reason. The stack trace pasted below does not have details on why it happened. Can you attach more logs from the transaction manager?

Also note that Tephra is now in Apache Incubator. I recommend using Apache Tephra mailing list for any future questions. More info on Apache Tephra mailing list is at https://mail-archives.apache.org/mod_mbox/tephra-dev/

Thanks,

Poorna.
