emagent spawing a huge number of LWPs after Solaris kernel patching to Solaris 10 U10

I can provide more details on patches applied, if required. I have a customer who has seen emagent spawn hunders of thousand of lwps after patching to 147440-08 (Solaris 10).

We have SRs opened on both the Solaris and database sides. Just checking if anyone has seen anything like this.
