[Bug 344447] [NEW] Memory leak in mysqld?

 

Public bug reported:


We recently upgraded to the ourdelta patch set (Centos5.2, x86_64, 5.0.67.d7-44.el5_2).  We were running the provenscaling version mysql).

Ever since the upgrade we seem to be having a memory leak in mysqld; the
executable is growing by about 3gb a day.  Here's an rrd graph of our
memory usage; you can see the "green" (apps) portion of memory growing
right after we performed the upgrade (at the end of week 8).

The application didn't change at that time; we are running the exact
same SQL queries and workload before and after the update.

I realize that I don't have enough info to allow you to fix any problems
in this but report (but if you can think of something we could measure
for you, I will).  But I did want to see if anyone else has seen any
leakage issues in this version of mysqld.

Thanks.
