Tool to detect memory leak in big C++ server application on AIX7.1 and AIX7.2

Question

I am making an VC++/C++ application in AIX7.1. Client system is made of VC++ and server is made of C++ and DB is Db2 v10.5. Compiler version is following: IBM XL C/C++ for AIX, V13.1.3 (5725-C72, 5765-J07) Version: 13.01.0003.0005

Server will upgrade to AIX7.2 soon.

I would like to detect memory leak of server application. I used to use Purify but Purify did not work properly because the application is too big.

Could you tell me the best software to detect memory leak?

Answer 1

The most famous memory debugger is Valgrind. There's no official indication that Valgrind supports AIX, but there are various people talking about running it on AIX:

• AIX 5.3 - Valgrind 3.3.1
• valgrind - pthread memory leaks on AIX

Another solution suggested by IBM is Debug malloc tool
