Zabbix items active checks

[testos]

Why any change in key active items type needs restarting agent for refresh itself?

[Alexei]

Wht do you think so?!

[testos]

Assuming existing /tmp/try/file1.log and /tmp/try/file2.log

1.- Create this zabbix agent (active) item with key: log[/tmp/try/file1.log]
All work fine

2.- Edit item above and change key to: log[/tmp/try/file2.log]
Changes aren't retrieved

3.- Restart agent (if possible)
One new line of file2.log is retrieved, but zabbix agent subsequently down

4.- Disable item
zabbix agent can be starting again

Restart of the agent is NOT required! Just wait for 5 minutes (default period) to allow the agent refresh list of active items.

I'm desperate.

I'm thoroughly revised this problem and in my system zabbix agent shoot down next creating active item key log[/tmp/try/file1.log].
I'm restart agent but when file2.log change first return one new line and next turn down.
In any case zabbix_agentd.log show this:

3002:20070620:104432 In process log (/tmp/try/file2.log,0)

  2997:20070620:104434 ZABBIX Agent stopped

I'm cheched this three things:

- ZABBIX server is running on correct first IP from Server to send active checks to, defined in agent's config file.
- Item log[...] is linked to hostname in agent's config file.
- /var/log/asl.log ir readable by user zabbix.
- Other active/passive checks, work fine for this host.

Please, help my

This problem is already fixed. You may try to use the latest code from svn://svn.zabbix.com/branches/1.4.1.

[testos]

For upgrade version only do replacing frontends directory or it is necessary to configure and compile all latest code?
