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.

0:000> !heap -s lfh key                   : 0x000000c5620647b0 termination on corruption : enabled           heap     flags   reserv  commit  virt   free  list   ucr  virt  lock  fast                              (k)     (k)    (k)     (k) length      blocks cont. heap  ------------------------------------------------------------------------------------- 0000000000430000 00000002  324032 319108 324032    111   126    24    0      0   lfh 0000000000010000 00008000      64      8     64      5     1     1    0      0       0000000000110000 00001002    1088    172   1088      7     6     2    0      0   lfh 0000000000ce0000 00001002      64     32     64     27     1     1    0      0       00000000015b0000 00001002     512      8    512      3     1     1    0      0       00000000011c0000 00001002      64     16     64     11     1     1    0      0       -------------------------------------------------------------------------------------

doesn't show particular leak.
