    high cpu load 100% with v2.2.1

    Hi all,
    i make a fresh v2.2.1 installation on FreeBSD 9.2 with postgres.
    After start from zabbix_server, i get high cpu load to postgres from zabbix.

    PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
    34688 pgsql 1 101 0 1050M 320M CPU2 2 19:05 96.97% postgres
    34694 pgsql 1 52 0 1038M 265M sbwait 1 0:17 48.00% postgres
    34669 zabbix 1 36 0 167M 54180K CPU1 1 5:23 25.98% zabbix_server
    34671 zabbix 1 47 0 163M 29224K nanslp 2 0:06 17.97% zabbix_server

    The system is currently not usable !
    I have "never" seen this on v2.0.x or old v1.8.x
    Why is the CPU load with v2.2.1 to high?

    PS: I see very similar problems with the performance !




    thx
    Stefan

    OK, i answer myself
    The value ValueCacheSize was too low, with 128M all problems are fixed now.
