we're using the OCEE Modul, which enables Transactions with InnoDB.
But the problem started as we updated Mysql and not only happens with
OCEE classes. I guess the problem appears in Connectionpool.
Has anybody experienced such problems with mysql 5.1.45? How about
configuration params of pool and my.cnf?
