WDB cannot attach to a process

Zul Kheraj — Tue, 26 Nov 2002 23:34:40 GMT

Hi folks

I am trying to attach to a process using WDB 3.1.1 and it fails with the following error
message:
Attaching to process 17391

Attaching to process 17391 failed. Hint: Check whether program is on an
NFS-mounted file-system. If so, you will need to mount the file
system with the "nointr" option with mount(1) or make a local copy
of the program to resolve this problem.

OS: HP 11.0
Binary running on /tmp (which is a logical volume)

Running wdb from /opt/langtools (which is again a logical volume group)

This is a standalone test machine without any NFS mounts.

Any suggestions

Did you get WDB from here?

Is the same user running wdb and suspicious process 17391?

Yes I got the depot from the HP site and the installation was okay without any errors.

Thanks for your suggestions.

Zul,

can you post a bdf and the file /etc/fstab? Also, is this machine on the network? What user are you running wdb with? Can you also post the command line you executed?

I'm still not convinced that you have the permission to attach to external process. You have to be either root or the same user as the owner of the process (to be honest - I'm not sure how is it with processes with setuid).

I know it's trivial explanation, but sometimes it's worth of checking basics first.

Good luck

Adam
