[daip] AIPS HELP

[Patrick P Murphy]

My apologies.  I meant to pipe in my $0.02 earlier, but didn't have time.
(I'm no longer with the AIPS group but help out from time to time with
system matters).

This is saying it can't find your message file.  Somehow it either got
blown away, or did not get created correctly.  If you empty the message
file from another AIPS session accessing that same disk (data area) as
"disk #1", then you can see this error.

They are generated when it says it's going to run FILAIP, then POPSGN.

It says there are no locks available.  That means file locking (using the
fcntl() system call) is not working on this particular (NFS-mounted?) data
area.  Once you peel away the errors about no message file, you see these:


> ZLOCK: No locks available
> FILAI1: ZCREA2: ERROR LOCKING SPACE LOCK FILE = DA00:SPACE
> FILAI1: ZCREA2: PERFORMING NON-ATOMIC FILE CREATION INSTEAD
> ZLOCK: No locks available

I suspect that the following:

> FILAI1: INSUFFICIENT SPACE ON DISK  1 FOR FILE DA00:BQD000000;

is a bit of a red herring.  It's best to solve the file locking issue
first, before digging deeper.  The way to solve it is to find your system
administrator (if that's not you) and see if file locking is enabled on
the system you're running on, and on the NFS server if that data area is
served via NFS from a remote host.  You want to make sure the "statd" and
"lockd" RPC services are both running.

I hope this helps somewhat.
