99% CPU After a few second amuled starts
« on: September 24, 2005, 01:08:10 AM »
I'm using the debian packages for amule 2.0.3+CVS, I start amuled with
'amuled -i -o' and after a few seconds the daemon starts (just after having connected to KAD and ED2K) it starts eating 99% cpu forever and ever....

I did 3 backtraces following the wiki, here they are:
(amule_2.0.3+CVS20050922-1_i386.deb Is the package currently installed, with all the others, all are 2.0.3+CVS20050922-1)

You're using "-i" to enable stdin.  Are you actually running this from a terminal?  In other words, is stdin a real source of input?  If it's /dev/null then I think there's a known problem: it keeps trying to read the command line, getting an error (or an empty command line), and looping back to read again.

Ken: you can't be serious. What does it have to do with command line ?! It never comes from stdin. Actually, I have no idea what is "enable stdin" is good for - stdin is not used in amuled anyway, and not get "disabled".

Hmm.  My mistake.  I could have sworn that amuled presented a prompt similar to what amuleweb presents.  It was pretty useless because it only supported a quit (or shutdown) command.  Maybe my memory is playing tricks on me.

lfroen,

Try to use valgrind, and you'll understand what is --enable-stdin used for :D

I would appreciate it if someone could explain to me if there is a solution
to the problem that this thread mentions.

I have 99% CPU utilization, and i don't know how to cure this.

Thanks

Yeah, well, one thread really is enough, you don't need to ask the same question twice.
