Can you let us know what version of Core, Plugins, and NSCA you have installed? OOM Killer is a common linux process which works to kill other processes in order to free up memory. How many passive checks are you hitting the Nagios server with?

NSCA has a number of issues at the moment.

You may want to downgrade NSCA to 2.7.2 by running the following

Code: Select all

    wget http://assets.nagios.com/downloads/nagiosxi/agents/nsca-downgrade.tar.gz
    tar xvf nsca-downgrade.tar.gz
    cd nsca
    ./upgrade

For us the use of nsca 2.7.2 isn't option because we can't use not syncronized hour checks with central server host. Last time we need apply a user based patch for making possible accepting non synchronized checks. We upgraded to 2.9.2 based in changes for more stability and one official way to accept non synchronized checks.

Also with NSCA 2.7.2 we have the same problem, a lot of nsca children process.

Is this a patch that your team created? I would try to turn on your debug logging to see what NSCA is actually doing after those forks. How many passive checks do you have hitting your Nagios system per minute?

I applied this modification to NSCA 2.7.2 for accepting future timestamp checks:
/* check the timestamp in the packet */
packet_time=(time_t)ntohl(receive_packet.timestamp);
time(&current_time);
//if(packet_time>current_time){
// syslog(LOG_ERR,"Dropping packet with future
// timestamp.");
// /*return;*/
// close(sock);
// if(mode==SINGLE_PROCESS_DAEMON)
// return;
// else
// do_exit(STATE_OK);
// }
//else{
packet_age= abs ( (unsigned long)(current_time-packet_time) );
syslog(LOG_ERR,"Time diff: %lu seconds", packet_age);
if(max_packet_age>0 && (packet_age>max_packet_age)){
syslog(LOG_ERR,"Dropping packet with stale timestamp -
packet was %lu seconds old or new.",packet_age);
/*return;*/
close(sock);
if(mode==SINGLE_PROCESS_DAEMON)
return;
else
do_exit(STATE_OK);
}
// }

Do you have another core system where you can test the current supported version of NSCA and then your modified version? When did this issue start to occur? And how many passive checks are you sending into the box and at what interval?

Re: Nagios invoked oom-killer

OK.

I have three system with 2.9.1 no modifications. In past installations I had modified 2.7.2 to accept not synchronized timestamp checks.

How can I check passive checks per second?

Re: Nagios invoked oom-killer

Just look at your services list and determine how many checks you have set up as passive, then measure from the last check time of the first one to the last one and see how many go through in one minute.
All times are UTC-05:00
