problems due to signal 11(SIGSEGV)

cent_sangeeta · 03-19-2013, 05:50 AM

Hello all,
MY Bug Reporting Tool reported two notices recently.

1.process/usr/bin/gedit was killed by signal 11(SIGSEGV).

2.process /usr/libexec/gdm-user-switch-applet was killed by signal 11(SIGSEGV).

As a result unable to open *.txt files using mouse. Also as I minimizes the the program , it simply disappears and had to use ctrl+tab to make it visible.

Thank you.

You MIGHT be having some hardware memory failures. It is not normal that gedit or gdm have such failures.

Thanks for reply. Is there any tool to check hardware memory failure in linux. What should i do against them?

Most distributions include the ability to boot the memcheck utility. It runs standalone and checks CPU and memory fairly well.

Hi,

As I mention at the very first that I am unable to open *.txt files using mouse and as I minimizes the the program , it simply disappears and had to use ctrl+tab to make it visible.

Is it possible to make those actions as normal as before ?

Thank you.

First you have to verify that the hardware is working.

All of your problems may be caused by bad memory.

Hardware memory problems are particularly likely to become evident in programs that use a lot of memory.

For instance I had a series of firefox crashes (but did not catch on to the cause) until the kernel crashed and I thought it was time to do memtest ... sure enough a fault found right away. Be prepared to run it for hours though to be more certain of good memory if no fault is found immediately.

Those crashes appeared in my server. I have been running wrf for simulation on it from couple of days and it's still running.
I think I will be getting trouble as I turn off my server.

Thank you.
