ZendServer killing my system after new install?

[chris_hird]

Anyone having issues with CPU after a new install? I am seeing 140% CPU utilization and its constantly creeping up?

Chris - we're having the same problem. Did you find the solution?

Any solution found yet

If yes please inform

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

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.
