Is this a bug or am I using GAM incorrectly?

I get ERROR: 500 when I run GAM in batch mode.  Here is what I am doing:

I am using GAM 4.94 on Windows 2012 R2.  

I have the following commands in a batch file called batch.txt that attempt to modify 3 settings on 2 groups:

gam update group AL...@rcdsb.on.ca update owner user us...@rcdsb.on.ca
gam update group AL...@rcdsb.on.ca max_message_bytes 25M
gam update group AL...@rcdsb.on.ca spam_moderation_level allow
gam update group BL...@rcdsb.on.ca update owner user us...@rcdsb.on.ca
gam update group BL...@rcdsb.on.ca max_message_bytes 25M
gam update group BL...@rcdsb.on.ca spam_moderation_level allow

If I run the batch file with only 1 thread, it works fine as follows:

set GAM_THREADS=1

c:\gam\gam.exe batch batch.txt
Using 1 processes...
 Group: al...@rcdsb.on.ca, us...@rcdsb.on.ca Updated to OWNER
updated group al...@rcdsb.on.ca
updated group al...@rcdsb.on.ca
 Group: bl...@rcdsb.on.ca, us...@rcdsb.on.ca Updated to OWNER
updated group bl...@rcdsb.on.ca
updated group bl...@rcdsb.on.ca

==================================

If I run the batch command with 2 or more threads, it fails as follows:

set GAM_THREADS=2

c:\gam\gam.exe batch batch.txt
Using 2 processes...
 Group: al...@rcdsb.on.ca, us...@rcdsb.on.ca Updated to OWNER
updated group al...@rcdsb.on.ca
updated group al...@rcdsb.on.ca
 Group: bl...@rcdsb.on.ca, us...@rcdsb.on.ca Updated to OWNER

ERROR: 500: Failed write includeInGlobalAddressList for group - 500
updated group bl...@rcdsb.on.ca

Have you tried running the command with CSV instead of Batch?

I rewrote my script to use the CSV method and it works.  Thanks for the workaround.  

I believe it works as the CSV method is only making one change to one group at a time using parallel processing.  Batch mode is failing as it is trying to change 3 settings on one group at a time in parallel.  

Is this a limitation of batch mode then?

Your wasting cycles making multiple API calls per group, multiple group settings can be changed at the same time and with one GAM command:

gam update group AL...@rcdsb.on.ca update owner user us...@rcdsb.on.ca
gam update group AL...@rcdsb.on.ca max_message_bytes 25M spam_moderation_level allow
gam update group BL...@rcdsb.on.ca update owner user us...@rcdsb.on.ca
gam update group BL...@rcdsb.on.ca max_message_bytes 25M spam_moderation_level allow

It's also the case that max_message_bytes is deprecated, you can omit it.

Thanks for the tip.  That makes my script much easier to update and faster to run.
