Transmission

brady7 and I confirmed that indeed our problems may be related, as posted by cfpp2p. We are both seeding torrents from the tracker he referred to in his forum thread.

@x190, that is an excellent idea. I should have tried this earlier. I will do this and post the results.

I don't think it's the same problem just because for me all torrents from http trackers are unable to connect, not just the ones from a particular tracker. Also, no luck with my special build of Transmission. I replaced the executable as x190 mentioned, but I don't know for sure if that means it act...

Still need some help figuring out where to change the compiler flags. I have no experience with Xcode, nor the Transmission code, so I'm pretty lost. I'm not finding them anywhere.

I've installed curl 7.40.0 via homebrew, but it does not replace the system's default version of curl. If I'm not mistaken, Apple specifies a version for all machines running a particular OS to use. In this case it was 7.30.0, which means that anyone running 10.9.5 should also be using that version ...

How do I determine what trackers are using UDP? curl --version outputs the following: curl 7.30.0 (x86_64-apple-darwin13.0) libcurl/7.30.0 SecureTransport zlib/1.2.5 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp Features: AsynchDNS GSS-N...

I flushed the DNS cache, and then attempted to get a debug log from curl. I had DHT, PEX and uTP disabled. Unfortunately, as the problem takes a whole day to reproduce usually, the log was around 300,000 lines. The problem definitely did still occur though, even after all that. I haven't bothered wi...

The problem started happening again.

@mike.dld, is there any way for me to determine exactly what torrent is hanging in 'write_all'?

@x190, I did not modify the torrent file. I do not wish to download using DHT since, as I understand it, private trackers don't support that.

I believe I may have solved the issue somewhat by accident. In looking at my message logs I noticed that there seemed to be one particular torrent that would appear to finish announcing, but then apparently do nothing further (judging by the lack of further messages). I did not notice this earlier b...

When that happens, it will not acquire any peers unless I restart Transmission. When I do restart Transmission, it no longer says "Announce in progress...", but "Next announce in [...]". Only then does it actually acquire any peers. As we've already determined, the tracker is not...

Unfortunately, the file was just a little bit to large for pastebin. I used tinyupload instead, I hope that's ok. http://s000.tinyupload.com/?file_id=07243415017838835956 I'm not sure how to interpret the log, so please let me know if it contains any clues. EDIT: I'm not sure if this is helpful to k...

But I don't like uTorrent... The only reason I mentioned it at all is because I used it to help troubleshoot, which I think is quite productive. By showing that uTorrent works when Transmission does not, I have effectively ruled out the possibility that Transmission is not the problem. Right? Also, ...

I ran the test for bit-torrent and there is no indication of either upload or download limiting. Regardless, that would not make much sense, seeing as the problem only happens sometimes, and even when the problem is occurring, uTorrent seems to work fine.

Do you have any other ideas?

The problem is currently occurring. No torrents will connect to any peers, and all of them are creating info messages that say "Scrape error: could not connect to tracker". Just as a test, I tried opening one of these torrents with uTorrent, and it connected and started downloading with no...

How do I check if DHT and PEX are working? Both are enabled. I know that the trackers are not unresponsive because if I restart Transmission the problem disappears, and it happens regardless of how many trackers I may be attempting to access at once (could be just 1, could be 5, but they all stop wo...

Had I been certain that this issue is particular to the Mac client I would have posted it there. In my message logs I am seeing a ton of info messages that say "Scrape error: could not connect to tracker", or just "Could not connect to tracker" after announcing succeeds. I have g...
