Can you run "gdb nagios" and get a stack trace and post it?   

When gdb initially gives a prompt enter "run -c <path>/nagios.cfg".  Then, 
when it gets "SIGSEGV", and you get the gdb prompt again, enter "bt" and 
then send the output.  This should tell where it died.

NSCA opens the Nagios command pipe, usually 
/usr/local/nagios/var/rw/nagios.cmd, which is closed and remade with each 
nagios restart.  The NSCA process must be stopped and restarted when nagios 
dies to open the new pipe. 
>>>> That's OK, but there is an option of Alternate Dump File which should 
work if the nagios  goes down. But nsca doen't append anything to it if the 
nagios goes down   
Secondly ,  Nagios is getting  Shutt down due to run time error ( SISSEGV), 
how do i find out a solution to that ?

Another option is to set up NSCA under xinet so it's started with each send 
request and the nagios.cmd command pipe is opened each time.  The downside 
is the process startup cost each time a check result is sent.  However, this 

usually works pretty well.

Hi all, 


I am using nagios-nsca-2.4  with nagios 2a 

The problems is that nagios  dies  after some time  ( I don't know why 
?) no errors .. just.. 
It says . 

1096321093] Caught SIGSEGV, shutting down.. 


Nagios Goes down and nsca processes getting stuck up.. 

Sep 27 16:43:52 monitoring nsca[12880]: SERVICE CHECK -> Host Name: 
'kirk2', Service Description: 'Check load', Return Code: '0', Output: 
'OK - load average: 1.01, 0.49, 0.18' 
Sep 27 16:43:53 monitoring nsca[12882]: Handling the connection... 

and nothing else .. 

This results in a endless number of processes making the monitoring 
server ( HANG) 

----nsca.cfg--------------- 
server_port=5667 
allowed_hosts=XX.YY.ZZ.00 
nsca_user=nagios 
nsca_group=nagios 
debug=1 
command_file=/var/spool/nagios/nagios.cmd 
alternate_dump_file=/var/spool/nagios/nsca.dump 
aggregate_writes=0 
append_to_file=0 
max_packet_age=30 
password=xxxxxx 
decryption_method=1 
-------------------------------------------------- 

But as per the configuration, it should have dumped the data to 
alternate dumped file but that doesn't work any clues ?? 

Regards, 
Sumit
