escalate this to SUN with your contract id. Only they can advise you on this

Hi,

I'm also hitting similar crash, which i'm not able to explain why.

Were you able to fix this issue - was it a bug in your code, or in SunOS.

Any comments would be of great help.

Thanks,
Krishna

hi krishna,
there was a bug in my code relating to arrays.
actually i was trying to fill the array beyond its size limit......

if u have gdb debugger it will be very useful to u.
else u try pstack core.
and look for the function where it is giving problem, in my case it was in "getHEXString" function .
most probably its due to arrays getting overloaded, so look for the arrays in that function, see what values are getting in to the function....

Rest if u have gdb debbuger it will tel u the exact line where this segmentation fault is occuring.

hope this works for u..
thanks

Thanks for the info.

I will check with GDB.
