Description

i can make Transmission crash on almost any large torrent. I mean 8GB and above. here are some examples. 

Mar  3 02:34:55 capslock [0x0-0x45e45e].org.m0k.transmission[55531]: /Users/mitchell/Desktop/Transmission_1.0x/libtransmission/peer-msgs.c:670: failed assertion `reqIsValid( msgs, index, offset, length )'

and another 

Mar  3 00:01:30 capslock ReportCrash[53594]: Formulating crash report for process Transmission[55357]
Mar  3 00:01:21 capslock [0x0-0x455455].org.m0k.transmission[55357]: /Users/mitchell/Desktop/Transmission_1.0x/libtransmission/peer-msgs.c:670: failed assertion `reqIsValid( msgs, index, offset, length )'

and my fix: 

2:45 capslock:~% cat ping.sh 
#!/bin/bash 

while : ; do
        ps auwx|grep -v grep|grep -i transmission
        if [ $? -ne 0 ]; then
                echo dead! `date` 
                open /Applications/Transmission.app
        else
                sleep 600
        fi
done
2:46 capslock:~%

the torrent file i think is causing the issue.

more crashes, different torrent file - but same files (ie. the repack of these episodes within a new torrent)

These are essentially the same crash report again and again, so you probably don't need to submit more of them unless you get a different trace in thread 1 or a different assertion message.

comment:5 follow-ups: Changed 14 years ago by charles

yeled: please re-trigger the error in r5189 and attach the console output. There should be about 10 lines that start with the words "(ticket #751)"; those are the ones that I need.

yeled: please re-trigger the error in r5189 and attach the console output. There should be about 10 lines that start with the words "(ticket #751)"; those are the ones that I need.

the boolean ( ! err ) was around the wrong way. it kept spamming my syslogd and the VM could not keep up and would bring the machine down.

I saw the error pop up once I changed the line to ( err ) and it came back as "err is 1" but then the kernel panicked (!) and the crash log was lost in the Journal...

do you need the exact log of the byte etc?

Could you make it crash again with r5204 or higher?

comment:10 follow-up: Changed 14 years ago by charles

If you do make it crash again, please attach both the console messages and the crashlog. thanks!

Fair warning: I'm not sure where this bug is coming from, so we may have to go through this dance again. :/

The bad memory on yeled's computer undoubtedly didn't help things, but after having that debug code in there for two weeks I finally got a hit:

False alarm -- those requests are coming from peers. :)

Is this still relevant? My log shows quite a lot of these messages. Can the debug code be removed?
