Hi all 

I just update sequoia from 2.10.0 to 2.10.10

We are running a volume test with 1000 clients sending insert transactions to the DB
We have 2 postgresql backends

After three hours we got these error messages and one backend was disabled

This did not happen with the previous version of sequoia

Any Ideas?

Thanks in advance
