[gembud] FW: no data written by dc* progs


I have no idea why this worked.  I re-generated my LDM pqact.* files from the 
gen_pqact.csh script instead of the gen_pqact_GEMDATA.csh script.  For whatever 
reason, the dc* decoders like to dump the decoded .gem files into the 
$LDMHOME/data symlink.  I just created another sym link inside $LDMHOME/data 
and pointed it to where I wanted the data to go, and now all is well.

HUGE THANKS  to Michael James for taking the time to look into this for me!

does this happen with all decoders or just some - are you getting at least some 
data ingested and written, and if that's the case, are the data written using 
FILE or PIPE in their pqact.conf entries?

Enormous Thanks for looking into this!  Please don't spend too much time on 
this.  I was hoping that there was already a fix.
Again, thank you for looking into this.  I'm very greateful for your time!

Michael, can you send me the log file which contains these "can not write to 
file" messages?

Also is SELINUX enabled or disabled?

Is there a soltuion?  I'd be very greateful if someone would share if there is.

I've disabled ipv6 on our system.

Here's a previous description that fits mine to the tee:

I've run into a problem with 5.11.4 where the decoders will not write files 
into $GEMDATA. If I wipe out the directory structure, the progs will create all 
of the proper subdirectories, but they will not be populated with data. In the 
various log files, all the apps complain about not being able to write to 
files. I've double checked the write permissions on the directories and ldm has 
write permissions (gempak was built under the ldm account, no gempak user.)
My system is:  Redhat Enterprise 4
Kernel is:   2.6.9-89.ELsmp #1 SMP Mon Apr 20 10:34:33 EDT 2009 i686 i686 i386 
There were no errors in the make or make_install logs that I could tell.
