Hi,
We are debugging an application and we are caught up inbetween that everytime there are vfork is generated. But there are no vfork calls ?

So Question is, what situations will vfork will be called ? Is there any way to prevent it ?

Or is there is any way to find out who calls this vfork ? as we are sure that our application does not have vfork calls.

Please help.

With Kind Regards,
Srinivasan S

Do you have tusc tool?? (Trace unix system calls)?? You can get here.

Yoou can start your process with tusc and see what is calling vfork()

tusc -vpf /tmp/trace.log "your_application"

The other tool that you may want to have a look at is "gcore" This will give you the core image of a running process. You will have to install some patches for it.
