Core Dump on Solaris (Question about core file)

dayalan_cse · 10-01-2007, 02:40 AM

Hello All,

I am getting segmentation fault on Solaris 5.8 but i could not find where the core file is being created. I did the following,

step 1: I did not get core file so i used ulimit -c unlimited
step 2: now my program crashed at the end it says "Core Dumped" but where is the file?

Am i missing anything here? Please let me know your inputs, Thank you in advance.

Thanks,
Dayalan

The core file is by default created into the process current directory. You can find what this directory is by using the pwdx command while the process is still alive.

You can also use the coreadm command to centralize core file storage.

Sorry, I could not find core file current working directory.

Any suggestions?

Thks,

How did you look for the core file and what failed ?

My suggestion is still to use coreadm. Did you have a look at this command ?

Hi jlliagre,

10 years later your post still helps !
On my old Solaris, I have found the core file hidden in a temporary directory using your command pwdx.
I had to add a system("read i") in my C source code as the core dump was too fast to get the process Id.

Thanks a lot!
