WebKitPluginProcess2 crashed with SIGSEGV in start_thread()

[regisz]

I do not know exactly why, but sometimes WebKit crashes.

Here is the backtrace: _usr_lib_x86_64-linux-gnu_webkit2gtk-4.0_WebKitPluginProcess2.1000.zip

Hello @regisz. It looks as a out-of-memory condition. Does your system have enough memory?

SegvAnalysis:
Segfault happened at: 0x7f8cf28e36ee: cmpb $0x0,0x2110(%rdx)
PC (0x7f8cf28e36ee) ok
source "$0x0" ok
destination "0x2110(%rdx)" (0x34db2e85e110) not located in a known VMA region (needed writable region)!
Stack memory exhausted (SP below stack segment)

sometimes google chrome eats my memory :(, but swap is enough

[jiri-janousek]

Well, it seems that's not enough for the flash plugin not to crash. Anyway, I'm closing this ticket as I cannot do anything but recommend increasing RAM. You may push this issue upstream to the WebKitGTK+ bug tracker though as the crash is in the WebKitPluginProcess2.

[regisz]

ok
unfortunately I can not increase the memory, now it is 8 GB, (and swap too).

I got the next message my bug report: https://bugs.webkit.org/show_bug.cgi?id=163485#c2
What do you think?

[jiri-janousek]

If you have installed the latest release of the Flash plug-in, then the only option is to pray for its stability. Alternatively, you can switch to a music service that doesn't require Flash.
