Hi,
I am running my application on two AIX 5.3 64 bit boxes. In one of the boxes it is running fine without any problems. But on the other box it fails as soon as it is started and it core dumps. When I was analysing the core I was able to find the below two lines in addition to other information.

pthdb_session.c, 818: 0 PTHDB_INTERNAL (internal error)
pthreaded.c, 1914: PTHDB_INTERNAL (internal error)

Does this mean that the box where the application is crashing doesn't have proper Installation of the pthread libraries. Please let me know. My application uses pthread functions.

Thanks in advance.

start by checking if there's thread support on the other box

I am also trying to debug a core file in AIX box . It is also giving the same error as

pthdb_session.c, 778: 16 PTHDB_INTERNAL (internal error)
pthreaded.c, 1778: PTHDB_INTERNAL (internal error)

I am not able to see any stack trace too. Please help me to solve this issue.

Hi,

I'm experiencing the same problem. After migration of my application from AIX 4.3 to AIX 5.3 if began to crash from time to time and coredump. Core analysis gave the following result:

pthreaded.c, 6405: PTHDB_CALLBACK (callback failed)
Illegal instruction (illegal opcode) in . at 0x0. warning: Unable to access address 0x0 from core.

Does anyone know what's causing this?

Currently the application is compiled on AIX 4.3, would compiling on AIX 5.3 be a solution?

Your help is much appreciated.

I believe so, binaries differ (system calls among other things?) from version to version on AiX, you defenitly need to re-compile
