Hi Edwin,

For an indication of the dump cause - run

what core

on the core file generated by the command.

HTH,
Jeff

would u like to see the core file?

Edwin,

the shell report segmentation faults of children as "Memory Faults". However, sysinfo call several other command... please use the "file" command to check what command really crashed.

Best regards...
Dietmar.

Wich parameters i need to use with file command?

[Alex Glennie]

"file core" will suffice ...

ps no 10 pts for me please ....

[Alex Glennie]

a thought ... do you have a file /var/tmp/exclude.temp how large is it and if you rename it or move it does the problem disappear ? it maybe a known issue if that's the case ....

[Edwin Ruiz_2]

No.. i dont have taht file on /var/tmp/

[Alex Glennie]

and the output from running file core ?

[Edwin Ruiz_2]

This is the output of file command

# file core
core: core file from 'more' - received SIGSEGV

[Jeff Schussele]

Hi (again) Edwin,

A SIGSEGV is a memory segment violation which usually indicates you tried to overflow a memory limitation such as one of the max?siz kernel parameters or that you exceeded swap reservation limit.
The message further indicates that the more command was running when it faulted.

Check the following kernel parameters
maxdsiz
maxssiz
maxtsiz
one of them may be very low.
Also run
swapinfo -tam
and verfiy that the reserve value is not near 100%. If it is you'll need to add more secondary swap.

HTH,
Jeff

Ok! thanks

[Alex Glennie]

OK what O/S and what version of sysinfo are we talking here : if you re-run sysinfo command does cpu increase and if you then run file core does it still yield a sigsegv from more ?

did you install the sysinfo binary : where did you get it from ....or did you build it yourself
