Segmentation Violation error

What could be the reasons of jBASE Segmentation violation error
i am trying to select financial files which are carrying huge data i.e in millions.
Be noted the T24 Release:: R8005 and jBASE version :: jBASE526

Below stats FYI


jsh ~ --> SELECT FBNK.RE.SPEC.ENTRY.XREF [having 10 million records approx ]
jBASE: Segmentation violation. Aborting


jsh ~ --> SELECT FBNK.RE.SPEC.ENTRY.DETAIL [having 70 million records approx]
jBASE: Segmentation violation. Aborting

Try setting ulimit in .profile as unlimited and select the file. Or else it's better to have some conditional select over huge files like this.

To be more interesting this behavior is not occuring on another environment :)
It is giving the correct record count.

Have you compared the ulimit settings between the two areas?

I have checked in both areas .PROFILE file.There wasn't any setting set for it
i.e ulimit variable was not in use.
Nevertheless i had set the variable as unlimited but the problem still persisted.

Not sure what is the problem. But you can check the following,
1. Is the file corrupted . use jstat -v filename
2. file is sized badly. use jrf -Rv filename

Nopes file in not corrupted i had already checked jstats
Also since table type is XMLORACLE so there is no point of file sizing.

i checked it was not unlimited
so set it with

>ulimit -d unlimited

the select query worked after it.
By the way what will be its implications on the system as a whole.

System will allocate full data segment resource for the current process/user. There won't be any implications.
Check Linux/UNIX help of this command in the web.
