That particular memory is freed in reading_get_done_handler(). I test with a memory checker in place that detects leaks, but that doesn't mean something hasn't been missed.
If you shut everything down, you can see if OpenIPMI has allocated any memory it has not freed. Look at cmdlang/ipmish.c to see how it does the memory debugging. Getting everything freed up can be a little challenging, but not impossible. Another option is to run under valgrind, mpatrol, or another memory debugger. Make sure to *not* run with the OpenIPMI memory debugger then. -Corey Noor wrote: >Hi , > >When i use below library call of OpenIPMI (1.4.19 or even 1.4.21) from >an application (linux 2.4.22), i notice a memory leak.
