E1: KER: Multi-threaded Kernels - Call Object Kernel Thread Pool Setting Message (Doc ID 652392.1)

Last updated on OCTOBER 31, 2018

Applies to:

JD Edwards EnterpriseOne Tools - Version 8.98 and later
Information in this document applies to any platform.


There are 5 Enterprise Servers and 5 HTML/JAS Servers, all running EnterpriseOne 8.11 SP1 TR 8.96_C1.  Each HTML/JAS Server is assigned an Enterprise Server for load balancing users across the system.  If a user logs onto HTML Server 3, this server uses serv-app3 for its Enterprise Server for all tasks (UBE, BSFN etc).  In the Hosts file, the HTML/JAS Server is pointing to the serv-app3 IP address referencing the name JDE.  So if the IP (serv-app3) is unavailable, it automatically redirects serv-web3 to serv-app4.  This seems to work fine.  However on some of the Application Servers, the following errors appear in the JDE.LOG:

9336/9252 MAIN_THREAD                         Mon Dec 18 16:38:27.630000  ipcmisc.c299
 process 9336 <jdenet_k> registered in entry 111

 KNT0000888 - Call Object Kernel Thread Pool in multi-threaded mode.
9336/9252 SYS:Dispatch                        Mon Dec 18 16:38:29.036001  Jdekdisp.c1924
 KNT0000999 - Call Object Kernel Thread Pool Setting: size 20, increment 5


This seems to happen every few minutes to an hour.  What happens is that more and more jdenet_k processes start in Windows Server SP2 until the machine runs out of memory and virtual memory and the system either crashes or becomes unresponsive.  If the server is rebooted, it works for a day or two then the issue happens again.
