Valgrind/memory leak question.

I'm trying to figure out a possible memory leak in my C program. I get the following message from valgrind:

16,020 bytes in 1 blocks are still reachable in loss record 1 of 1
at 0x4A04B32: calloc (vg_replace_malloc.c:279)
by 0x38932D57BF: monstartup (in /lib64/
by 0x400B4B: __gmon_start__ (in "my app".o)
by 0x400B6D: (within "my app".o)

definitely lost: 0 bytes in 0 blocks.
possibly lost: 0 bytes in 0 blocks.
still reachable: 16,020 bytes in 1 blocks.
suppressed: 0 bytes in 0 blocks.

This doesn't seem to happen with any of "my" memory allocation (none of which are of 16020 bytes). Is this leak "my fault" - is there anything I can do about it? It happens quite randomly - I can try to do the excact same operation several times, and it's a 50-50 chance I'll get this error or "No leaks possible".

Any help would be very much appreciated!
