Ok so this is part I need help part heads up for others. The back story... I a client messaged me saying that they couldn't save posts anymore for specific entries. I noticed the ones that were having issues were the larger ones. The entries are fairly complex with the supertable plugin. I tried EVERYTHING I could to diagnose the problem, modifying every server setting etc. I realized it worked locally but not remote. I also realized it worked fine on my phone but not my machine. it worked on a co-workers air but not my macbook pro. craziness. I did eventually get it to work but I'm not sure why.
Switching out of DevMode made everything work fine, but that isn't a real acceptable solution for me because I use devMode. I hope anyone struggling with this, sees this but I appeal to some of you more seasoned Craft devs, why the heck is this happening in devMode and only remote on some machines?
