1.4.2 postgresql problems

[thresh]

Hello.

I've got a bunch of hosts monitored by zabbix (~150).

Zabbix server dies all the time with something like this:
 28112:20071203:163835 Query::insert into trends (clock,itemid,num,value_min,value_avg,value_max) values (1196686800,22041,1,1.000000,1.000000,1.000000)
 28112:20071203:163835 Query failed:PGRES_FATAL_ERROR:ERROR:  duplicate key violates unique constraint "trends_pkey"

 28112:20071203:163835 Query::update items set nextcheck=1196689145,prevvalue=lastvalue,lastvalue='1',lastclock=1196689115 where itemid=22041
 28112:20071203:163835 Query failed:PGRES_FATAL_ERROR:ERROR:  current transaction is aborted, commands ignored until end of transaction block

 28112:20071203:163835 Query::select distinct function,parameter,itemid,lastvalue from functions where itemid=22041
 28112:20071203:163835 Query failed:PGRES_FATAL_ERROR:ERROR:  current transaction is aborted, commands ignored until end of transaction block

 28078:20071203:163835 One child process died. Exiting ...
 28078:20071203:163837 ZABBIX Server stopped

I've tried deleting all the data from trends table, still the same.

Suppose it is a bug; where should i file one to be fixed?

zabbix 1.4.2, postgresql 8.0.14.

I've also posted a bug to bug tracking system, still no reply... anyone ?
