SvcHost for NSI Network Store Interface High Memory Usage

windows server 2008 standard sp2

i'm working on issue svchost.exe uses lot of memory. on several weeks, grow gigabyte , continue grow. i've broken out services each run own process , have determined service nsi - network store interface.

i'm have reason believe in way related application software running on machine clueless determine api calls cause service leak memory. have dump file can provided quite large - approximately 300 megabytes.

edit: happening on server 2008 64 bit. not server 2003, not r2, not server 2008 32 bit. when terminate application, memory usage on svchost.exe plummets. application related in way.

edit 2: have been doing debugging of dump file.

doesn't show particular leak.
