These aren't error messages. You can tell because they say "INFO".

A ZEO storage server only commits one transaction at a time.  When a
client is ready to commit a transaction, and another client is already
committing one, the first client is "blocked" and has to wait. These
messages tell you about the status of blocked transactions.

ZODB 3.10 is far less chatty on this topic.
