trapper: interrupted system call

[marcelein]

Hi everyone,

i know that problem was discussed in this forum before but i cant find any solution that works for me.
i have some trapper items but im not recieving any data with them.
if i run the script that collects the data on my system and gives them to the zabbix sender manually i can see latest data in my zabbix frontend
if this script is executed by the zabbix agent i got some errors in my zabbix server log:

21844:20080602:154330 Timeout while answering request
21844:20080602:154330 Get value from agent failed. Error: ZBX_TCP_READ() failed [Interrupted system call]
21844:20080602:154330 Host [zabbixagentdhost]: first network error, wait for 15 seconds

manually the controller item is not beeing updated

my zabbix server and agent version is

zabbixserverhost:~ # zabbix_server -V
ZABBIX Server (daemon) v1.4.5 (25 March 2008)
zabbixagentdhost:~ # zabbix_agentd -V
ZABBIX Agent (daemon) v1.4.5 (25 March 2008)
Compilation time:  May 20 2008 15:05:33

maybe i upgrade to server 1.5.2 beta?
i was there before but my frontend didnt worked correctly there was some files missing (dontknowanymore.php) but i liked the frontend so maybe someone could parse me some working frontend script and i test that issue with some beta server versions

thats for helping me out

btw. my server and agent is running opensuse 10.1 (will upgrade in the next days)

How many trappers do you start in your zabbix_server conf file? I had a similar problem when I was starting only a few trapper listeners but was sending larg amounts of data.

I am not sure if this will fix your problem completly but I am thinking it is a good place to start on the problem.

Have fun!

i was on the default 5 now i check with 25
my errors now:

23900:20080606:170806 Get value from agent failed. Error: ZBX_TCP_READ() failed [Connection reset by peer]
 23900:20080606:170806 Host [zabbixagentdhost]: first network error, wait for 15 seconds

do i have to raise to trappers in my agent config too?
thx i have a new point to work on

It depends on how much data is being sent from the agents. I don't know exactly what is being sent so 5 may be too few or it might be the perfect amount. I would leave them default until you have reason to believe otherwise.

As for those errors, if you do a few searches on the forums you will find others with possible solutions. Let me know if you havn't found a solution that works for you and I will see what I can do to help.

Have fun!
