Topic: Amuleweb crashes often (Read 6155 times)

ivano77 · « **on:** June 17, 2006, 03:52:33 AM »

I tried both 2.1.2 and 2.1.3, all the packages posted on amule webiste but there is nothing to do, sometimes soon...sometimes after a while amuleweb crashes, first it takes huge memory and lot of cpu time then is probably killed by the system.
Amule is a grat project and is perfect as it is now...should only be more stable
thenk you

Regarding the error message: Have you installed libgd and pibpng?

The segmentation fault seems not to be connected to this, it happened for me as well while just clicking through the windows.

Code: [Select]

This is amuleweb 2.1.3

Creating client...

I hope this helps. (Will now try out CVS)

lfroen · « **Reply #5 on:** June 18, 2006, 06:52:02 AM »

Do you have some browser accelerator (like fasterfox) installed? I suspect that reason for a crash is many simultaneous requests (for image) in the same time.
Can you reproduce the crash in predictable manner ?

ivano77 · « **Reply #6 on:** June 21, 2006, 02:19:26 AM »

Yes! i had fasterfox and i removed
In fact now crashes after a while and not soon as before
i had again few "segmentation fault"
and the last was this one

I have the same sort of problem : amuleweb seems to crash randomly. I've attached gdb to it, here's the tail of gdb's output :

The different threads are probably, as you said, simultaneous requests for images (namely, the progression bars on the transfer tab). I don't have Fasterfox installed. I'll now try to refresh the page automatically and often, but after having disabled images in Firefox. We'll see if it crashes. If you want me to compile amuleweb from source with debugging symbols, to have a more clear output of gdb, just ask. Right now I have the FC5's packaged version installed, from the Livna repo (v2.1.3-1.lvn5)

[EDIT: smilies disabled to avoid trashing gdb's ouput]

Did you reconfigured Firefox to do it ? By default, it will not issue simultaneous requests (AFAIK)

I haven't changed anything regarding this on Firefox : I must have the default 1.5.0.4 behavior. I didn't know it wouldn't issue simultaneous requests... Then if it's not simultaneous requests, they're at least very close, which is not surprising as I'm connecting on the loopback interface, so this is quite fast. Here are a couple of parameters of my about:config in Firefox (which are the defaults), if it's of any interest to you :

Code: [Select]

network.http.max-connections=24
network.http.max-connections-per-server=8
network.http.max-persistent-connections-per-proxy=4
network.http.max-persistent-connections-per-server=2

And about the test without images : I couldn't make amuleweb crash, even refreshing each second for several hours. Only one thread is created each time (the webpage itself).
So it must definitely have something to do with the mass-thread creation (when images are activated in the browser).

lfroen · « **Reply #11 on:** July 06, 2006, 04:07:23 PM »

This is what causing FF to issue (or not) next request BEFORE previous complete.

Code: [Select]

network.http.pipelining=false
Any way, backtrace log with debug info would be helpful. Without debug info it confirms that some problem exists, but give very little hint about where it is.

I can confirm this is set to false on my installation too.
