[SR-Users] 500 Forking capacity exceeded (12/SL)

[Camila Troncoso]

Jorj,

Do you mean that the branches are represented each one in one bit, so 32
bit number is a max of 32 branches?
And you recommend to use value 30, leaving 2 bit reserved?

Regards,

Camila

Sadly, the branches are tracked in a 32-bit number, so you can't make it
to 40. (We use 30 at Penn, having found a couple bits reserved.)

We've done some preliminary work trying to migrate this to a 64-bit, but
it's not complete, and we're not actively working on it any longer.
