Printing

[Jäger Helmut_1]

I have severe problems with printing:
Version: Compaq Tru64 UNIX V5.1B (Rev. 2650); Fri Nov 4 10:49:47 CET 2005
Patches:
- T64V51BB25AS0004-20040616 IOS540
- T64V51BB25AS0004-20040616 OSF540
- T64V51BB26AS0005-20050502 IOS540
- T64V51BB26AS0005-20050502 OSF540
When I try to print some files with "lp" or "lpr" then I will get the following error:
Memory fault
And no print is done!!!

Any help would be accepted with pleasure!!

What is the output of lpc stat?

Is the lpd daemon running?

Check your filesystem space.

Verify the cksum of these files, I will post the files in mys 5.1b pk5 chksum:

960818503 191728 /usr/lbin/lpd
960818503 191728 /usr/lbin/lpd
960818503 191728 /usr/lbin/lpd

Run this also:

/usr/lbin/fverify -n < /usr/.smdb./OSFPAT02606900540.inv
/usr/lbin/fverify877758 (0) begin logging at Fri Nov 4 07:48:27 2005

0 verification errors encountered.
0 corrections performed.
/usr/lbin/fverify877758 end logging at Fri Nov 4 07:48:27 2005

No errors should be reported.

In attached file you can see my results.
I'm surprised, because the verify says, that no files for lpd, lpc, .... are not existing, but they are real existing. So I'm worrying in this case!!

What to do?

Kind regards

[Ivan Ferreira]

I forgot to methion that before running fverify, you need to do:

cd /

Have you verified the cksum for the files also?

[Jäger Helmut_1]

Now I did the verify from / and no errors were reported.
I also have the same chksum with /usr/libin/lpd!

I found this:
http://ftp.support.compaq.com.au/pub/patches/Digital_UNIX/v4.0d/DIGITAL_UNIX_V4.0D/doc/txt/OSFPAT00118800425.abs

But I think, this is for Unix 4.0x, but the same message and errors!!!

[Ivan Ferreira]

Is this the only problem related to memory. Any other application/command with the same issue?

Does the dia command reports any errors?

I saw problems like this (in other linux version) that was solved by running fsck, in this case, verify.

[Johan Brusche]

A "Memory fault" is not a HW error, but caused by a program trying to access memory that is NOT allocated to itself.

A "Memory fault" normally leaves a core-file
behind in the cwd. One can examine this core with : ladebug /usr/bin/lpr core.
Then the 't' or 'where' command shows the program stack.

Maybe /etc/printcap got scrambled . You can check for errors in the file and the associated print environment with the command "lpc check all"

You could then post the results....

Agree, you can use cat -e /etc/printcap to check for non printable characters. You can also copy that file and start with a basic printcap file with just one printer to see if the problem persists.

Thanks for your efforts!

This ist the output of the ladebug:
# ladebug /usr/bin/lpr core
_bsd_tgetent() failed with status 0
Welcome to the Ladebug Debugger Version 69 (built May 4 2003 for Tru64 UNIX)
------------------

The "where" command has failed because there is no running program.

This is the output of "lpc check all":
/etc/hosts.equiv: Access is restricted to about 2 hosts or netgroups.
/etc/hosts.lpd: Access is restricted to 1 hosts.
all: unknown printer
No configuration problems found.

I tried also to start with only one printer (created with lprsetup), but with the command "lp dPrinter test.txt" it gave me the same error:
memory fault

Some suggestions???

[Jäger Helmut_1]

Now it seems I found the error:
I copied the "printcap.dat" from an old Unix 4.0 System and some Parameters (like zf or Pc) are not supported under V5.1.
When I started with a new (clean) printcap.dat, I also did set this parameter by hand, because I did believe, I need them.
With a really clean new printcap it now works and I can print!!
Many thanks for your help!!!

I did find the solution as I posted before!

Thanks to all!
