Transmission locks up my whole system!

[ohaiwill]

I've been using transmission for a while, starting on my hackintosh, and now onto my macbook running snow leopard. I'm a pretty big torrenter, having about 800 transfers in the client. Sometimes, for a reason unknown to me, transmission freezes, then my browser stops working (won't load pages, just says loading), and then everything freezes. I can't even do a proper shutdown or restart, I just end up holding the power button and forcing a restart that way.

I've been trying to figure out the cause, but haven't had much luck. Sometimes it seems like it happens with larger torrents downloading (~7 or 8 gigs), and sometimes it seems to happen if i change the bandwidth limit.

Is this a known bug? Anything I can do to help get this fixed? It's a huge problem for me, and I even ended up switching to uTorren (until i realized it sucked and decided a buggy transmission would be better than it )


EDIT: After a bit of searching, I guess a lot of people are having this problem. Here's the solution I tried:

Create a non-rich text text file (best by using TextMate or TextWrangler) with only following content in the file:

Code: Select all

    net.inet.tcp.rfc1323=0
    net.inet.tcp.recvspace=32768
    net.inet.tcp.sendspace=32768
    net.inet.tcp.win_scale_factor=1
    net.inet.tcp.sockthreshold=0

After that, save the file as /etc/sysctl.conf

Normally, when you choose "Save As..." in any Mac OS X application, it won't show you the directory "/etc". In order to let it show it, choose "Save As..." and then type "/" in the save dialog. When you enter "/" , it will show you a textfield. Enter "/etc" and push return. The save dialog will then show you the content of "/etc". Now enter the filename "sysctl.conf" and hit "Save".

I've never used textwrangler, but I'm assuming that when you create a new document it's non-rich? Oh well. I did what this guy said, and hopefully it works!

yeah i still get these whole system lockups pretty often (i started a thread about it somewhere). the fix you posted didn't help for me, hope it does for you tho.

so far i haven't experienced the crash again, but now i'm having trouble connecting to peers and downloading. i'm going to try without that fix now and see if it's causing it.
