Nagios Support Forum

(Hope I didn't cause too much confusion since I already posted this=

message once bevore beeing a member of this list.)



Hi All,



I'm facing the problem, that the pre flight check from nagios causes=

a segmentation fault, if the 'member' variable of a servicegroup=

contains a '*' wildcard. I have just compiled the latest CVS tarball=

because there have been some similiar bugs reported, but it didn't=

fix my problem.



This is the part of my configuration that causes the problem:



# causes seg fault

define servicegroup{

servicegroup_name Swapspace

alias Services checking the swap space on=

disk

members BSS-MGMT-SMServer*,Swapspace



}



Of course there is at least one host which matches the pattern 'BSS-MGMT-=

SMServer*,'.

Seems the '*' after 'BSS-MGMT-SMServer' causes the problem. If I=

switch to a single host name, everything works fine:



# causes no seg fault

define servicegroup{

servicegroup_name Swapspace

alias Services checking the swap space on=

disk

members BSS-MGMT-SMServer-Test04b,Swapspace

}



I run Nagios in GDB. This is the output:



>nagios-2-x-cvs/base # gdb nagios

(gdb) run -v /usr/local/nagios/etc/nagios.cfg

Starting program: /root/temp/nagios-2-x-cvs/base/nagios -v /usr/local/nag=

Maybe this will give someone of you a hint, what might have happened.=

(I was a little bit confused about the last modified date of 05-31-2006,=

but I'm shure I got the latest tarball.)



Maybe someone has help. Thanks in advance.
