Process stuck on windows server 2003

Question

I use rrd(build version 1.4.7) as part of my project. The rrd executable is periodically called by my process to update the value. And sometime RRDTool process stuck after calling update operation.


There's 2 thread in the stuck process, here's the thread stack. It seem like the process is already finish its task and about to exit. Does any one have an idea about this thread stack ?
