traplog info

[Piyu_86]

Hello all
i dont have much knowledge about traplog

under /var/log traplog is getting generated .
what for this traplog ? can anyone suggest any site from where i can get info about generation of traplog . I searched in the net but unable to find any relevant thing.

You running any sort of snmp? They can be configured to create a traplog. What is in the file?

i am getting traplogs when passing sigbus signal

in my code i have done SIGBUS signal handling.

void
sigHandle(int xx)
{
switch(xx)
{
case SIGHUP:
printf("sighup");
//code --
break;
case SIGINT:
printf("sigint");
case SIGQUIT:
printf("sigquit");
case SIGBUS:
printf("sigbus");
case SIGTERM:
printf("sigterm");
//code --
break;
default:
break;
}

now inside my main function i have defined a signal handler

struct sigaction sa;
sa.sa_handler = sigHandle;
if(sigaction(SIGBUS, &sa, NULL) != 0)
{
//print message
}
similarly for othersignals


the code is not generating trap for other signals but particularly for sigbus signal it is generatin trap . ?

Is there any specific way by which i have to do signal handling for SIGBUS ??

check the trap file to see what is being written to it. It might be the information from your code.

as per the designlogs and trap logs

when i am sending SIGINT signal it it is passing thru all the cases and ends with sigterm(as break is there at teh end of sigterm) , similarly for other signal but the trap is mainly occurring when we pass SIGBUS signal.

date:time: process:EE: fault.c(152): 9486:9486: Generating TRAPINFO for: pid=9486[process name], tid=9486[process], sig=7

SIGBUS is defined as Sig 7
