threaded C Program hanging in dld.so

[Maddy_81]

Hi,

I have a C program which is hanging intermittently with the below stacktrace.

(gdb) where

#0 0xc000000000081a50:0 in __siginhibit+0x50 () from /usr/lib/hpux64/dld.so

#1 0xc000000000081d50:0 in apply_lazy_iplt_reloc+0xe0 ()

from /usr/lib/hpux64/dld.so

(gdb)

It is running on HP-UX 11.31 ia64. Does anyone have any suggestions please?

Thanks

Do you have the latest linker/dld patches?

Have you contacted Support?

Thanks a lot Dennis for replying back.

Can you please let me know if there is any specific linker/dld patch which is proven to resolve this issue?

[ShridharJoshi]

what linker/dld patch you are using? ($what /usr/lib/hpux32/dld.so). Check using the latest linker/dld patch.

does the application hangs permanantly or hangs for some time and recovers?

Is it multithreaded?

can you corner out the issue in test case?

I am using the below patch.

92453-07 linker dld HP Itanium(R) B.12.58

Yes, it is a multithreaded application.The application doesn't recover. It just hangs there.I am not able to go beyond the error on dld.so however i tried. So wanted to check if it is a known issue for which there is a fix available.

B.12.58 is older patch. Check if the issue reproduces with latest linker patch.

Hi,

Thanks for your reply about the linker patch. As suggested, we have installed the below B.12.62 patch. But it didn't help. I am still facing the same issue.

       92453-07 linker dld HP Itanium(R) B.12.62

Any suggestions please?

Again, have you contacted Support?

You could always use bind immediate which stops doing BORs (at the cost of slower startups and possible unsats):

chatr -B immediate executable
