You need to find out in which system call the processes are
stuck. If it turns out to be the fcntl call on the
secrets.tdb, then Jeremy is right that it is a Veritas bug.
If they are stuck somewhere else then we need to look
further.

strace -p <pid> 

on such a process might show you the syscall where it hangs.
