I am facing an issue with memory management in AIX 5.3. My Process crashes with malloc/calloc failure. But it is allocating and freeing all the memory when required. I have run svmon command for several times and found that pgsp value is growing continuosly. here is the output for two times taken after six hours:

here pgsp and virtual memory values are increasing. My questions are:
1) Does it concludes to a memory leak?
2) If yes, then how can it be solved?

Thanks,
