Hi everybody,

This is my first post, cause I'm newbie in aMule to Mac. I'm running aMule 2.2.6. Have an iMac 2.8 Intel core i7 with OSX 10.6.4.
Well, few minutes after connecting aMule my iMac gets totally crashed. I should force a restart, using the iMac rear power switch button, try to force program exit doesn't work.

I was looking for the forum, but my english seems it's not good enough to learn how to report properly this crash, furthermore I didn't get any OOPS! aMule crashes message, simply my Mac crash.

If somebody can help me to try to solve or know what to do, I appreciate.

Thanks in advance, and sorry fro my english.

Your Mac shouldn't crash no matter what amule doing. Do you have any third-party system software installed (firewall? device drivers?). You don't see "OOPS! aMule crashed ..." message because as you already said it's your system crashed, not amule.

Try to examine system logs after restart and see what part of kernel actually crashed.

[salakazam]

Thanks for the answer lfroen,

Maybe I'm not express properly, maybe due my english maybe my lack of experience in mac. You're right, aMule doesn't crash, I guess the proper word is freeze, aMule gets freeze, then when I try to force the program exit is my mac whose gets freeze, and should force the machine restart.

I'll try to check the system logs next time, but first need to know where they are, lol, then I guess need to know how to read properly.

Thanks again.

Well, I found the system log an how to open it (console). I was right, I have no clue about how to read or understand it.
When froze happens again I'll check the logs trying to know, maybe will ask again in case someone can enlighten me.

Thanks, regards.

It happens again, this time I could force the exit of aMule without restart my mac. I was looking the system log file also.
As I said above I'm not sure how to understand the logs, but seems aMule got frozen when Time Machine backup got an error, without aMule running backups works fine always, but with aMule I got this message:

Aug  2 09:26:29 iMac-de-Sal-Akazam com.apple.backupd[419]: Starting standard backup
Aug  2 09:26:29 iMac-de-Sal-Akazam com.apple.backupd[419]: Backing up to: /Volumes/Time Machine/Backups.backupdb
Aug  2 09:27:03 iMac-de-Sal-Akazam com.apple.backupd[419]: No pre-backup thinning needed: 25.08 GB requested (including padding), 182.33 GB available
Aug  2 09:37:36 iMac-de-Sal-Akazam com.apple.backupd[419]: Error: Flushing index to disk returned an error: 0

What do you think? I'm gonna exclude the aMule's dowload folders from TM and try again, do I should exclude aMule's temp folder too? or anyone else?.
If don't work I'll try shutting down the TM backups to see.

Thanks in advance, regards.

Definitely exclude aMule's temp folder. There are probably many large files in it that get changed very often - this will overfill your time machine.

[salakazam]

Thank Stu, I did it but nothing change. AMule still freezing about 30 minutes after I run it. This time without TM running.
And no clue what system log is telling me:

Aug  2 10:53:49 iMac-de-Sal-Akazam mDNSResponder[33]: PenaltyTimeForServer: PenaltyTime negative -31555, (server penaltyTime -1059157825, timenow -1059126270) resetting the penalty
Aug  2 10:53:51 iMac-de-Sal-Akazam com.apple.launchd.peruser.501[161] ([0x0-0x3c03c].org.amule.aMule[577]): Exited: Killed


I guess second line is the forced exit of aMule. But don't know what's the first one, can be related to a temporary internet lost connection? Cause when aMule freeze my news site doesn't refresh, maybe is aMule itself whose cause this lost connection...

Thanks again, regards.

How much memory do you have?

[salakazam]

How much memory do you have?

In my iMac? 8GB 1067MHZ DDR3.

Thanks for the interest, I still trying to work properly, but something happens. Any suggestion will be welcome.

Regards.

Do you have ntp enabled? Is there any ntp message on the logs?

[salakazam]

Do you have ntp enabled?

Do you mean network time protocol? to synchronize date and time internet way? Then yes it's enabled.

Is there any ntp message on the logs?

In system log appears every once in a while lines like this:
Aug  9 10:17:41 iMac-de-Sal-Akazam ntpd[22]: time reset +0.149695 s

I'm not sure if you are asking me about I answer above, if not please excuse my ignorance, I'm just a humble mac user. Tell me if you need to know something else.

Thank you anyway. Regards.

Your answer was perfect, actually. I am wondering if the negative DNS penalty is caused by NTP adjusting the time forward (like in your log) and causing the time difference for the penalty to go backwards (from the mDNSresolver source).

While the DNS message has most probably nothing to do with aMule, the NTP difference could be the root cause. Could you try to disable NTP in the date & time preferences and try running aMule for a while, so we can rule that out?

Of course, I'll do and let you know what happen.

Thanks for the help.

[salakazam]

Nah! Didn't work.
I disable NTP and the screensaver, cause aMule seemed frozen in 30min, my screen saver settings. This time aMule freeze in an hour.
When aMule was frozen my internet connection got lost too, but only in my iMac, e-mail or browser don't work. My PC still working fine (I mean is not my DSL router or internet provider). That's weird to me.

Well, I'll keep trying. Thanks for the help.

Good to know it's not that. You use wireless to connect, right? Does the same happen when connected via cable?

Just clearing some possibilities here.
