Topic: what is chumbpipe

We are running a series of flash experiences.  We seem to be building a large number of instances of a process called chumbpipe.

What is this?  Should I be concerned that we will eventually choke on this volume?

from a ps -ef

Re: what is chumbpipe

I currently have 124 instances of chumbpipe running.  Doesn't always generate one when I issue a chumbyflash player, but it often does.

should I killall instances when I start a new flash movie?

Re: what is chumbpipe

"chumbpipe" is a program that is used by Flash Player to talk to other apps - it's used to avoid creating forks within the player itself.  I'm not sure why you're seeing this behavior.

Re: what is chumbpipe

So we now go ahead and killall chumbpipe eachtime we start up the flashplayer.  Doesn't seem to have caused any harm and the list of processes does not grow.

Although I think there is still some memory leak somewhere.  It takes about 8 - 10 hours to eventually bring the system down.

Re: what is chumbpipe

There was a bug related to incorrect spawning of chumbpipe in the Flash Player, but we fixed it for regular Chumby devices.  I'm not sure what version of the player the NeTV group is using.
