Hi friends,

I am developing a multithread program on solaris platform. In one of the functions, which is being called inside a thread, there is a very huge array of a large structure. (Instead of creating on heap, it is created ON STACK, i.e. local variable of a funtion).

I tested the program using Rational purify. When I increase the size of the structure or the array size, the purify gives a sequence of BSWs (beyond stack write error) and BSRs (Beyond stack read error). Obviously, this problem has something to do with the thread stack limit.

1. Why does purify give beyond stack write and beyond stack read errors and not "Stack overflow error"?

2. How to find out the thread stack limit on a particular system? Is it configurable?

If I run the same code segment inside a process (main thread) I don't get the above BSRs and BSWs.

Thanks
