Hello,
I still believe there is a small leak. I see 8K
increments not everytime
the below code is called. It sounds like a race
condition in mysqlpp.
Has anyone attempted to 'purify' this code to validate
whether the methods leak? When the 'use' statement is
not used and I dont cycle through the table rows which
results in an eventual exception 'end of results' then
there is no leak.
I'm going to try to get a version of purify next week
and run this
code through it.
Thanks,
Garyc
