[Solved] Palemoon instability since v19

Postby drivetheory » Fri Apr 26, 2013 2:31 pm

ever since Palemoon transitioned from v18 to 19 and now to 20 it's given me problems... I'm not sure if it's an addon, a plugin (java, flash, etc), or what.

In version 18 with all my addons I had zero problems (yes, ZERO PROBLEMS), then version 19 came out and I started experiencing the quirk where I'd X-out of palemoon but the process would still be running (and process explorer details would always show 1 really busy thread with a plethora of cycles delta) forcing me to kill it via process explorer... mind you it was random, as in i'd see this behavior occur maybe once or twice every handful of days (so 1-3 times per 20+ hours of usage, or every 10+ launches of the program, can't give exact numbers sorry).

then with version 20 now I'm experiencing less frequent of the above error, but now palemoon will randomly lock up / become unresponsive, i think it's related to page rendering but can not be certain... sometimes it will freeze when scrolling, sometimes it will freeze when typing a web address in the address field, sometimes it will occur when opening the bookmark dialog...

I've since recreated my palemoon user profile, and tried testing via divide and conquer (disable 1/2 the addons, wait for crash/hang/freeze, disable 1/2 again, etc) but since the hang/freeze is so random i haven't been able to narrow it down yet... and i think the latest flash player is problematic since videos now hang/freeze then quickly speed-up to catch up (like almost as if there was a traffic jam on my ISP and all the packets just arrived at the same time... or they were all stuck in a buffer or something...) but that's a different problem since the hangs & freezes don't occur in correlation to flash player (the container process never hangs, only palemooon.exe)

anyhow, aside from addon divide and conquer and swapping flash player versions in and out is there a better way i can troubleshoot this problematic behavior? like if some code executing is looping or in a wait state or whatnot is there a way i can go about testing/checking this? Palemoon never crashes.... it just gets quirky.. I haven't had a process hang in days but it did freeze for a couple seconds on me maybe 2 hours ago when i was trying to enter text into the address bar while a webpage was loading...

attach windbg and......? or (insert some programming related task i can try to fumble through here)?

so, I posted the above, then i disabled another couple addons and checked for updates to the rest of the addons (which there were a few) then went to close palemoon and sure enough it hung. First hang I've had all week...

so i took a screenshot of some useful info (i hope) and attached it here.

also threw adplus @ the palemoon running process, 7z'd the results except the .dump file since it's too large to be attached.

any and all information i can provide just ask please

OK, odd to begin with that you say you used Pale Moon 18 - it doesn't exist.

As far as the hang is concerned, I'll have to have a look at this in more detail when I get back home so please be patient.
At first glance it hangs in the JS subsystem which most likely means there is a hang in one of the javascript processes. This could likely be chrome related since it doesn't release the thread, but that still leaves the possibility of internal UI, or theme, or addon, so it doesn't narrow it down much.

Try running without addons for a while to see if that solves your issues.

was a misnomer on my part re: the v18 bit. having been troubleshooting this problem for a while now my memory lapsed at the version number, yeah, i should have posted earlier when the problems first started happening but i thought i could figure it out on my own...

oh no worries, i've got plenty of patience = )


EDIT: looking at my browser history im seeing palemoon 15.4.1 (x64) as the version i had previous to 19 (can tell by the EXE filename downloaded)

previously i posted about this, but that was an old pc and an old install of the OS, and i never finished ruling out extensions (was without a PC for about a month, long story, blame lightning + humorous CATV grounding specifications in the electrical code).

Now I have new PC, with a new install of the OS (win7x64), a new install of Palemoon (20.2.1-x64), and a new profile (except i did import a bookmark backup)
Installed just over a dozen extensions , some big (NoScript), some small (Open Image in New Tab)...
and after a couple days palemoon finally hung. so for the past couple days i've systematically disabled all the extensions 1 by 1 until they were all disabled.
Palemoon hung on closing about 20 minutes ago with all extensions disabled (the window went away as always, but when i tried to relaunch it a few minutes later the popup about it running but not responding appeared).

What can i do to help you help me stomp out this bug/quirk/problem/etc?

If you could use whatishang on your new install with everything in add-ons disabled when you get the hang, I can compare it with your previous submission and see if there are parallels or if this is a separate problem.
What are you using for system software in terms of firewall, antivirus, internet security and similar? Any processes that might interfere with system run-time operation for Pale Moon?

palemoon is currently hung as i type this. using google chrome to post.
last thing i did in palemoon was rename a bookmark and click the X to close the program, lol
whatishang does not list palemoon as hanging...
no av atm, nothing should be interfering with palemoon while it's running

and about 90% are windows + driver related software
not sure what the entire 101 were in that screenshot
the attched screenshot has 95, so im gonna guess and say missing are probably notepad++, photoshop, thunderbird, a 2nd instance of palemoon.exe and whatishang, maybe 1 or 2 other similar type windows, note sure, don't remember.

EDIT:
in case you are wondering, the screenshot is a merged image of 2 screen caps
VivaldiFramework.exe is associated with the MegaRAID Storage Manager
PnkBstrA.exe is related to anti-cheat protection for video games
everything else has descriptions and company names so...
(and, yes, palemoon is still sitting there hung, waiting)
