Hi ,why SIGBUS Error ?

[Cai Wenliang]

hi, all
I am a developer worked on hpux11i+Oracle+Orbix. Now I encount a big problem -- My server process coredumped by receiving signal 10. It has runned smoothly in the past week. I have also taken care avoiding memory leak or involid memory access in my program .
below is the information generated by gdb:

anybody can told me how to do ?
any help are appreciated greatly .

Seems you could have a problem with either kernel parameters (maxssiz/maxdsiz/maxdsiz_64) or your application has encountered some out of bounds memory address. Suggest you download and install tusc, and trace what the application is trying to do.

You can get tusc from here:
http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/tusc-7.3/

[A. Clay Stephenson]

A register dump is of very little use; you need to use gdb to do a stack trace. That will pinpoint the exact error.

I don't know the gcc compiler options but the ANSI C compiler option that you need to use is -g. That will include symbolic data for the debugger in the executable; do not optimize at all as that will distort the debugger data.

Rm all your .o's; change the compiler options to use -g; do a make and do not strip. Execute your code and allow it to dump core. Now, when you use the debugger you can generate a stack trace, it will display the call stack and even give the source file and line number. With that you should have no trouble finding your bug --- and it is your code somewhere.

[Cai Wenliang]

but the machine my program runned on isn't allowed to install any more software. So I have to debug my program by only core file.

[Cai Wenliang]

anybody can help me ?
Is it possible that it is oracle's or orbix's fault ?
I am lost in sea.

[Steven E. Protter]

Its always nice to blame oracle, but in this case the dump file seems to say another application did it.

Perhaps oracle made the application do it.

What has changed since last week?

If its nothing, examine your oracle binaries, especially the ones involved in the error.

I have had several instances of oracle binaries mysteriously changing size and becoming corrupt. It caused all kinds of problems, Oracle blamed it on the disk(right, raid 1 mirror/ux).

I tracked down the problem binary and used scp to copy it to the affected system.

Relink Oracle.

Never a bad idea.

su - oracle

$ORACLE_HOME/bin

you can use

$relink all

which will re-link all the executables.

Make sure that you set your
$ORACLE_HOME/lib in your SHLIB_PATH variable.
If you are using 64 bit oracle version make sure also you have $ORACLE_HOME/lib64 in the SHLIB_PATH variable.
