Change multiple pools in one curl REST API command

Some more info on this issue. I haven't mentioned that we are using Jenkins build server to deploy our site on our servers and use the F5 REST API to disable upgraded servers. When I'm writing a shell script and run it from a certain machine, so far, all is working good. When I'm running the same script (copy and paste) from a Jenkins job, it sometimes work and sometimes doesn't. We have asked F5 support and all they have suggested us to do is to use tcpdump on the F5 machine. I actually want to know what happens on the F5 transaction wise. Before committing the transaction, is there any way I can see which commands are attached to the transaction? If all the commands are attached to this transaction as should be, is there any other log that can show me what's going wrong?

Thanks Gil
