I have installed ZCM 11.3.1 on SLES11SP3 the third time, to different customers virtualized on Citrix XEN. Without any device in ZCM (standalone server only) the vCPU 0 in Citrix-Xen-Center shows near 100% cpu-utilization. SSH slow response, ZCC is slow. With "top" on console I identified processes like java, jsvc and dbsrv12 as the processes with high cpu-ultilization.

Before this we have ZCM 11.2.4 and versions before this some years on Win2003-32bit, same virtualization-platform Citrix XEN without this problems. I have test different vCPUs, from 1 to 4 and different RAM-Sizes, 4 - 8GB. I try to set the independent wallclock and NTP, inventory schedule for the server to "monthly", no success. Some ideas?

Thanks Heiko
