Memory leak in Windows Live Messenger?
July 17, 2006
I downloaded the final RTW version of Windows Live Messenger a few days ago and it had been working well for the most part. Rose had mentioned that Messenger seemed to be crashing her computer, taking up almost 100% CPU and over 150MB of RAM. I thought that sounded a bit high, but her computer (my old IBM T30) is 4 years old, so I figured maybe it was just that it’s a bit outdated.
But lo and behold, a few hours later, my computer started getting really slow – quite a surprise since I wasn’t doing anything really and my computer is a totally decked out Pentium D 930 with 2GB of RAM and a 10k RPM SATA system drive. I looked in taskmgr and I see msnmsgr.exe going crazy at 48% CPU and using over 200MB of RAM (and the mem usage was growing while I was watching it). Looks like there might be a bug in there…
Note to Windows Live Messenger folks who might be reading this: it seems like a long haul bug. It only seems to happen after the client is running for a long time. Normally my messenger uses < 60MB of RAM and takes up < 10% CPU, even when I’m running a 2-way video chat session. Let me know if you need more repro details. Thanks!
