Issue/Introduction

Every Sunday L-Serv is stopping and coming up with the following error:
IEF352I ADDRESS SPACE UNAVAILABLE

Last week we raised a change to up the region size from 64M to 128M however we are still getting the above error.

Is there any issues with this?

It starts straight back up once it has ended, would you recommend increasing the region size again?

Why do I have the message IEF352I ADDRESS SPACE UNAVAILABLE when L-Serv stops?

Environment

CA COMMON SERVICES 14.1 - LSERV 14.0 - z/OS supported releases -

Resolution

Here are the information about this message:

IEF352I ADDRESS SPACE UNAVAILABLE

z/OS issues the message when an address space uses space-switching PC routines.

When ending a batch job, started task, or TSO user, the initiator/terminator found that this address space had been used to provide services to other address spaces through space-switching PC routines.

In order to maintain system integrity, the address space is ended and is marked as unavailable.
This does not necessarily indicate an error in the program or in the initiator.

LSERV uses space switching PC routines so this message is issued when LSERV is shut down.
It's normal for LSERV, the message doesn't cause any problem.
