Bon Echo seems to be hanging on me at random intervals without any sensible way to reproduce the error(s).  It has been happening to me since B1 was released to the public.  I was thinking perhaps this was originally a cousin of #346308 but it doesn't seem to be that way since a fix was tracked in to fix that (and my issue predates 346308).

Reproducible: Always

Steps to Reproduce:
1.  Start Bon Echo
2.  Navigate around the web

Actual Results:  
Bon Echo will eventually stop working -- most notably around sites with a lot of activity such as Flash, AJAX or similar things.  The CPU usage on the processes list will spike up to 100% and the memory usage will go as high as 128k and it eventually will hang out and die (without TB incident btw!)

Expected Results:  
It should not do this?

I am at a *TOTAL* loss for words on how to reproduce this or even get any information back off this problem.  All I can say is it started on B1 and has NOT relented since the fix for #346308 was checked in.

It is less recurrent now that that fix is in place which leads me to believe I was suffering from two separate bugs with the same symptoms.  I'm totally willing to run debug builds or anything needed to track this.  However, I'm unable to get any reliable information from any possible ways I know how so far.
Could this be a duplicate or a possible side-effect of 346233 ?
Depends on: 346233

I did not realize it until later, but SteveE pointed out that the time my bug started pre-dates that of 346233 so it's unlikely it is a direct result of it.  It could be a bug which was contributing TO 346233 though, that's possible :-*

Hang != crash. I doubt there's much we can do here without a stack for the hang. I think you will need to get a Windows debugger and somehow attach to the process and get a stack.

Are you using any extensions? If so, can you try using Bon Echo for a day or two without them and see if you still see this?

Well, I know a crash and a hang are different.  It does both, hangs then crashes out :)

No extensions, running a new profile and safe-mode both produce the error as well.  Affirmative on the debugger idea, I'll give that a whirl when I have some free time to toss around.

Okay, I was looking at a website recently and the browser locked up and refused to do anything.  After a couple of minutes Dr Watson interrupted and told me a memory dump and a log were created of the incident, I grabbed them for your viewing.  See attachments.

I had no place to upload the dump file so I put it on YouSendIt (lame huh?)


^ dump-file for your downloading pleasure.

David, you might want to ping timeless on IRC to figure out how to go about analyzing that log file. I'm really not sure how to do that (nor am able to since I'm on Linux).
A hang was recently fixed in bug 346233, so it's possible that this bug has been fixed. Please leave a comment if you are still able to reproduce this with a recent nightly from the branch, otherwise we'll close this as fixed.

Looks like this is fixed now.  I will poke around with it some more but I haven't seen it since the fix was put in, which is a really good sign.

nope, still happening.  I will ping Timeless about this later tonight and see what he thinks :-)

This has not happened for almost a week now.  I am going to go with resolved on this one.  I'll see if I can figure out what landed and fixed it however, it's fixed so that's all that's important. :-)
