Everytime I run Transmission, my ram usage eventually goes through the roof. It happens across all of my Macs running 10.6.1. Eventually, all the ram is used up and I have to restart to clear it up. If I don't run transmission, no matter how long I leave my machine running, my ram usage never goes past 1G Used. As soon as I launch transmission, within minutes or an hour(s) it's so sporadic the ram usage hits 3.5 used or more... All my macs have 4GB of ram. iMac aluminim, white macbook, and unibody macbook pro 13"
Right... that's exactly what's baffling me. I can't figure out what's using up 3.xGB of ram... and it's the same on all my macs... as long as I'm running transmission... if I never startup transmission, ram usage stays below 1 or at about 1GB. For example on one of my macbooks, I rebooted and left it idle for one hour. Ram usage never went above 1GB. I restarted and did the same for another hour. Same result. I rebooted again and opened up a few torrents and started downloading... within an hour this was the ram usage (see image attached) I never launched up another application (Other than Safari to post this).
I have the same problem as funkycarter. If I boot my machine and load nothing except Transmission then within 10 minutes most of my ram shows in Activity Monitor as "active".
Just because Activity Monitor doesn't say the memory is allocated to Transmission doesn't mean it's out of your hands IMHO. I'm thinking you may be doing something like calling some disk cache function which is causing this issue.
OK, I just downgraded my Transmission from 1.75 to 1.74 and ran it for a few hours. Memory didn't get used up like it did with 1.75 From a cold reboot I have only 420MB RAM marked as active in Activity Monitor (when it was previously more like 3.5GB)
Flunkycarter, can you try downgrading your copy of Transmission and see if you get the same result?
