Iam using IONA Orbix. the environment is like Windows platform C++ handshakes with AIX application servers thru Orbix.
AIX application servers are crashing and producing a core dump. the same binaries are perfect in different machine.
DBXing on the core dump -
Segmentation fault in pth_usched._usched_dispatch_front [/usr/lib/libpthreads.a] at 0xd0055c94

Since my server application doesnt deal with threading, iam concluding this wouldnt be due to code issues. Now how do i confirm if this is due to Orbix setup or AIX problem.
