I gave up the first time they asked me to record data for them during an 
instance and wanted us to let it hang and collect data.

I was like no, not going to do that.

And then started removing 1072 connection tracking altogether from my network.

For the time being I’m using 1036 for CGNAT as a transition, then will head to 
CHR CGNAT, then Juniper.

I agree that Mikrotik just isn’t focused on the 1072 anymore and this 
particular issue seems beyond them to repair.

Which makes the 1072 a no starter for anything conn track for us ever again.

I’ve got one 2004 doing the CGNAT now, and it’s on latest Stable release.
Watching to see if it bails too, or is capable of doing it for the time being.

But our end game it MPLS/VPLS and/or direct switch VLAN type segmentation of 
layer2 into our cores where we will do all of the heavy lifting.

Subject: [AFMUG] Mikrotik Official Limitations

Still fighting with Mikrotik about the 1072 reboots.  New hardware didn't fix 
it, had several people check the configs all were good. After 2 months of going 
back and forth, escalating to a higher tier tech...   I officially got a 
response that 1 million connections is too much for the 1072 and I should 
expect it to reboot and not function properly.  That was their conclusion.  
Even though all of the 72 processors are under 50%,  memory usage is only about 
20% etc.  Turn off connection tracking is the their solution.

How about those apples?
