Sqlservr.exe Handle Count Of 3,306,263

Hi,

I have asked this question on the MSDN forums
with no response as yet. Maybe you guys can
shed some light on this:

We have an apparent File Handle leak occurring in our SQL server.
Last weekend the server ran out of non-paged pool space:

Event ID 2019 -The server was unable to allocate from the system
nonpaged pool because the pool was empty.

In the process monitor the sqlservr.exe process had Mem Usage
of 503,528KB and a handle count of 3,306,263 (!). Using poolmon
the highest usage of the non-paged pool was for the Muta tag, with
211,610,768 Bytes. Restarting the sql service fixes this
temporarily, but already we are back to 427,000 handles for
sqlservr.exe and climbing steadily at about 200,000 handles
per day.

Is there a fix for this?

Cheers,
Geoff
