Subject: Re: SSI update

Hello Sir,

Apology for the confusion, Recently in one of my test system I added a
subsystem to SSI and i have started experiencing recursive abends. After
adding I started seeing some of the STC which were started taking more Real
storage(Which Usually doesn't take much during normal).
