How much do I need to worry about this?

Thu May 14 14:55:44 PDT 2009

I have been having a similar problem.  I thought it was just with some kind
of duplicate declare... but today, I put this...

     if: mid(d_fld["1"],"1","1") eq "A"
then:  blah blah

and it did what it has been doing on this 5.6.6 version of rcabe.  It gives
the syntax error , and then when I press ENTER, it gives another syntax
error... but then immediately drops back to the shell.  It should not do
that.  The rcabe program usually/always puts you back in the prc table on
the line with the error, or close to it.  In the past few weeks to amonth or
so I have been seeing this other behavior.... rcabe crashing out.  Very
strange.

I thought mid(array[element],x,x) on the left side of an if comparison was
allowed.  It never used to be, but it was fixed some time ago ... along with
mid of a lookup  in the same place (left side of a comparison on the if
line.).  I *know* these were fixed... but today, the mid of an
array(element) failed. I had to put the value in to a variable and then mid
the variable.

What is there an "R" in the month or something... no... a "Y"... ahhh,
that's it.

 Well, I guess you mean a comment on the if: line of a lookup.  I

don't

think anything other than the lookup can go on a lookup line.  But,

still,

shouldn't cause rcabe to crash.  It's sounding like an overall

memory error.

I didn't understand what you were saying about your testing on other

machines.  Did it not crash there so you think it is just on your one

development machine?  Is it at all repeatable?  Have you eliminated

hardware

problems.  Re-seated the memory, simple things like that?

The problem happens when I have a syntax error in the table and

occurs no matter which machine I use in the office.  I checked the

log on Samba and it seems to be opening and closing the files as

necessary and isn't complaining about anything.

I also tried copying all the files from the file server onto my own

machine and set PFDSK to the local disk and I still got the problem.

This should have eliminated any memory problems (wouldn't duplicate

on other machines) and the server (I'm running the programs off the

local disk).

I do know one error that causes very strange behavior with cabe... I

don't

rmember if it does actual crashes. It might... Though... I know it

does all

sorts of weird stuff.  This is the error of not having enough memory

allocated to "label" size. There is an environment variable that can

be set

higher.  PFLBSIZE.  As you get more and more lookup aliases, array

names I

think, and actual labels, maybe some other things, Ken would have to

elaborate, the tables can not be saved properly and lots of strange

runtime

errors occur.  I set it in most of my large systems to 5000.  I

think it is

defaulted to only 1024.  Like I say, it probably doesn't cause cabe to

crash, but then again, that might be one of the symptoms.

This couldn't be the problem as I can make it do this even if the

only line in the table is a lookup with a syntax error.

One thing more....I'm seeing the following on the screen right after

the error window pops up:

Exception error -1073741819 in process failed 0(0x00000000)

comspec="(null)"

command="\fpro\fp\rcabe

         "

Press Enter:

Are you running a WINDOWS version of filePro?  I had the impressing

you were running a Unix/Linux version from the talk of Samba.

I had no end of issues with filePro when the Windows network is not

working correctly.

The errors were like SegViolations on Unix and reported like you see

above.  It always seemed to be caused by the system being unable to

write fast enough.

Now mostly I saw this in the runtime side, but maybe your network has

other problems.

To fix my RUNTIME issues, I added SLEEP commands after WRITE or

CLOSE

to give the network time to write the data and update the server.

It fixed most of the problems.  It has reduced them to the point where

they are very  occasional, instead of crashing so much we could not

work.

Check that you have applied all the network patches for the system,

especially related to LOCKING and I/O, for the server and clients.

Hope that will help.

Thanks for the in depth responses, Nancy.

I am using FilePro running locally on Windows machines and using a Linux

server running Samba as the fileserver.  (When we made this change we

were already running FP Windows off a Netware server, so moving to Samba

when we needed to upgrade seemed the logical decision.)

I have no problems with rclerk or rreport.  In fact everyone else is

moving along fine without even knowing about what is happening (except

for my having to explain why I can't get anything else done right now).

The error occurs as soon as I enter 'Y' at Check Syntax.  Yes, it saves

the file, but it won't compile it.

To isolate the problem I moved everything over to my own local machine

and change PFDSK to point to the local drive.  It still happens which

means that it isn't related to the server.  I also get the same problem

on other machines so it can't be a memory issue.

I ran Microsoft's FILEMON to see what the system was doing with the

files and I did find one interesting thing when I looked at the data.  I

found that rcabe was looking for 3 files that I can't find on my system.

273    2:53:40 PM    rcabe.exe:360    QUERY INFORMATION

E:\fpro\fp\WINSTA.dll    NOT FOUND    Attributes: Error

274    2:53:40 PM    rcabe.exe:360    QUERY INFORMATION

E:\fpro\fp\WTSAPI32.dll    NOT FOUND    Attributes: Error

275    2:53:40 PM    rcabe.exe:360    QUERY INFORMATION

E:\fpro\fp\SETUPAPI.dll    NOT FOUND    Attributes: Error

I have sent FPsupport this information as well as the complete FILEMON

data from the error.

Just crashed rcabe 5.06.07 Windows.

Here is what caused the crash

Cn(len(1),edit(1)=2

Note I left off the closing paran. ).  The syntax check found the error and

pointed at the =.

Not sure if this was your problem, but this is my error and it did crash

rcabe.

Upgrading to 5.6.07 seems to have resolved the problem.
