Memory leak problem- An interesting solution

I came across a memory leak problem. It is interesting that Solaris 10 provides a very good mechanism with the help of libumem.so library and mdb debugger to solve this problem. The following steps help to identify memory leaks.

• $export LD_PRELOAD=libumem.so
• $export UMEM_DEBUG=default
• $ mdb  ./myTest
  
• > ::sysbp _exit
• > ::run
• > ::findleaks

If you find the following error message

• "mdb: invalid command '::findleaks': unknown dcmd name"
  

then the workaround is

• >::load libumem.so
