view full story

http://www.unix.com – We have our in house developed software running on AIX 6.1 (6100-06-06-1140). The application is a 32 bit application and the operating system is 64 bit. We are running this application without any issue on AIX 5.3 32-bit on P5. We are facing issue with this application after moving on P7 with aix 6.1. The application runs for the almost 2 to 3 hours and then crashes generating core dump. The application team is saying there is an issue with memory allocation for 32 bit application on 64 bit OS. We have checked vmstat and found no memory bottleneck. We have inserted an entry i (HowTos)
