Same here... I've found that after debugging some php code, these jobs run away consuming a lot of system resources and a kill of all the zend jobs and restart the server is a work around but not a solution.

Is the server unresponsive?
Are you getting any other log entries?

Which version of Zend Server are you running.

We are running Zend Server Version 9.1.0 on V7R3.

I don't think we've seen the high CPU utilization yet, but we have received a few errors on the ZSDAEMON jobs.

Code: Select all
Message . . . . :   Space offset X'00000000' or X'0000000060000000' is outside
   current limit for object ZSDAEMON  QTMHHTTP  684518.                       
Cause . . . . . :   A program tried to set a space pointer, tried to use     
   storage outside a space, or tried to use an unallocated page in teraspace. 
   The space class is X'08'. The space class designates the type of space:     
   00-primary associated space (includes space objects). 01-secondary         
   associated space 0. 02-implicit process space for automatic storage.       
   03-implicit process space for static storage in activation group mark       
   X'0000000000000000'. 04-implicit process space for heap identifier         
X'00000000' in activation group mark X'0000000000000000'. 05-constant space.
06-space for handle-based heap identifier X'00000000'. 07-teraspace offset   
X'0000000060000000'. 08-teraspace for System i5 PASE memory address         
X'0000000060000000'. Offset X'00000000' only applies to storage outside     
teraspace. X'800000000000000000008000B0000000' is a pointer to the teraspace
page or the start of the implicit process space for the allocation.         


Are your ZSDAEMON generating a lot of error logs and continuously restarting?

I experienced both issues, I believe they are unrelated.

1. new install killing my system
We found that upgrading from ZS5.6 to ZS8 required a huge increase in resources (memory & CPU)
Zend advised we needed minimum 4GB memory and a full CPU allocated to the partition ZS is running in.
Try disabling the various Daemons using the 'Autostart Job Settings' menu in the configurations part of ZSMENU
Also disable ZRay.

An alternative we researched was running the PHP on a Linux server and connect to the Iseries for DB and program calls (DB2 Connect must be purchased from IBM).

In the end we had to purchase a new IBMi server!

2. Teraspace Memory Problem
We also had this problem on ZS9.1 (V7R1).
The solution was to run the '41. Reset Zend Server environment' option available in the maintenance menu of ZSMENU
This routine clears memory.
I now have a CL routine that runs every night when restarting the Zend Server.
