Originally reported by Oli Sennhauser at http://bugs.mysql.com/bug.php?id=20629 Description: When we run a benchmark script which need for the PT Workshop. It gives an error with too many concurrent connections. How to repeat: # perl benchmark-sql.pl --flush=0 -c 1 -n 10000 --schema=world -e "select 1" Total Time is: 1.0333 Number of Iterations: 10000 Number of Clients: 1 # Time/Query Total Time Query --- ---------- ---------- ----- 1. 0.00010 1.03315 select 1 1. select 1 # perl benchmark-sql.pl --flush=0 -c 5 -n 2000 --schema=world -e "select 1" ERROR processing SQL statement #1: select 1 DBD::mysql::db do failed: Lost connection to MySQL server during query at benchmark-sql.pl line 132. at benchmark-sql.pl line 132 eval {...} called at benchmark-sql.pl line 132 # perl benchmark-sql.pl --flush=0 -c 25 -n 400 --schema=world -e "select 1" DBD::mysql::db do failed: Lost connection to MySQL server during query at benchmark-sql.pl line 112. at benchmark-sql.pl line 112 Original file to repeat the issue is hidden, but I was not able to find a way to put hidden file into this user interface. So, please, if you need test case, let me, or some other Oracle employee who has developer access to bugs.mysql.com, know how to send it privately.
