# - ttl with milliseconds resolution 'ttl a 1000'. Check ttl in dump!

jzawodn / bdb_mysq_leak.pl
Created June 14, 2013 18:33
Demonstrate the leak in DBD::mysql that I noticed. If you fail to connect (down host), the program will leak memory. If you're connecting to a server that's up, there is no leak.
