agentd 1.6.4 Win32 increases the consumption of memory and stop run

[Luciano Komosinski]

I have 4 servers running Windows 2000 Server running zabbix_agentd.exe (32 bits). When the active monitoring of the Zabbix server, Zabbix the agent increases the consumption of memory on the machine and the agent stop run.
Shooting only the command (zabbix_get-s10.30.2.18-p10000-k "system.uptime") in the Zabbix server, I receive the error message below and also agent zabbix stop run:
"zabbix_get [32011]: Get value error: ZBX_TCP_READ () failed [Connection reset by peer]"

Someone saw something with zabbix agent 1.6.4 Win32?

This problem is linked to perf_count

The items that are causing this problem using the key perf_counter. Disabling the items with this key the agent zabbix does not fall. This problem is linked to perf_count ...

[Alexei]

We will try to reproduce it in our test environment. Thanks for the details.

Machines with Exchange

The machines that had this problem have Exchange installed.

The items we collect in "Perf_counter" are:

perf_counter[\MSExchangeIS Mailbox(_Total)\Send Queue Size]
perf_counter[\MSExchangeIS Mailbox(_Total)\Receive Queue Size]

perf_counter[\MSExchangeIS\RPC Requests]
perf_counter[\MSExchangeIS\Maximum Users]
perf_counter[\MSExchangeIS\Maximum Connections]
perf_counter[\System\threads]
perf_counter[\MSExchangeIS Mailbox(_Total)\Message Opens/sec]
perf_counter[\MSExchangeIS Mailbox(_Total)\Logon Operations/sec]
perf_counter[\MSExchangeIS\User Count]

perf_counter[\Network Interface(MS TCP Loopback interface)\Bytes Received/sec]
perf_counter[\Network Interface(MS TCP Loopback interface)\Bytes Sent/sec]
perf_counter[\Network Interface(HP NC7770 Gigabit Server Adapter)\Bytes Sent/sec]

perf_counter[\Processor(_Total)\% Processor Time]
perf_counter[\Processor(0)\% Processor Time]

* Also to run "system.uptime" the agent drops in these machines

Problem with the Perf_count & SMTP service and MS Exchange

We note that this problem with the Perf_count occurs on machines that have the Windows 2000 SMTP service and MS Exchange Server 2000 installed. In other machines that do not have these services installed, we use the Perf_count to collect items without any problems.
