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.

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 ....

This is the output of file command

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

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 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
