Getting core dumps daily at 00.03 to 00.13 on zeus process

>ksh: unpackcore:  not found

unpackcore and getcore are gdb commands.

#0 0xc0000000003b46f0:0 in strcmp+0x50 /usr/lib/hpux64/libc.so.1
#1 0xc00000000050e1c0:0 in do_getconfig+0x3e0 libc.so.1
#6 0xc0000000005b1af0:0 in getpwuid+0xf0 libc.so.1
#7 0x400000000006a940:0 in <unknown_procedure> + 0x170

This indicates you are either:

1) Passing something bad to getpwuid, hard to believe since only a uid_t.

2) Something wrong with getpwuid and what it calls

3) You corrupted the libc globals

Also as you mentioned the below points

This indicates you are either:

1) Passing something bad to getpwuid, hard to believe since only a uid_t.

2) Something wrong with getpwuid and what it calls

3) You corrupted the libc globals

The libc.so files are provide by HP to us. so do we need to contact HP for the same issue.

Thanks

>(gdb) getcore

Only needed if you exit gdb and want to continue later.

>The libc.so files are provided by HP. so do we need to contact HP for the issue?

Yes, libc is part of the core system.  They are going to want that packcore.

And they are going to want you to get your patches up to date.
