My apology if you get a duplicated email. We found out ""Could not get JDBC Connection; nested exception is java.sql.SQLRecoverableException: IO Error: Got minus one from a read call" happened very frequently, almost every uPortal.log.
Any inputs will be appreciated.

During our load test, we found out "Could not get JDBC Connection; nested exception is java.sql.SQLRecoverableException: IO Error: Got minus one from a read call" happened sometime on some tomcat instances. Anyone have been experience this? Would this error have any impact to your environment? Any idea why this happened? How can we fix it? Highly appreciate your help.
