[097] Memory leak detected [1260 bytes]

I have received the following error my SQL Server Agent Log.

[097] Memory leak detected [1260 bytes]

When this happens jobs will fail with the following error.
[000] Unable to retrieve steps for job Backup TLog - 1stComp (Increm)

My current work around is to stop and restart the SQL Server Agent services.

Has anyone seen this before? Is it corrected in the the 2153 hotfix?

What is the service pack level on SQL & Windows?

Also the memory leak errors seems to be hardware related too, might invole the Vendor to confirm the health state of hardware.

|||It's SQL Server 2005 SP1 64Bit Enterprise Edition.
The server is a Dell poweredge 6850 with 8 Physical CPU's 64 GB of RAM
Windows server version 5.2.3790 SP1 build 3790.

I should have encluded that in my original post.
