ADTopkek commented on ASTERISK-25852:
-------------------------------------

The problem was the Max stack size. Its set to 128 by default in asterisk. We were using FreePBX so every parking lot we had took up 1 stack, every outbound route took 1 stack, and modules took up a random amount. All together it went over 128 till it started causing stack errors. We had about 50 parking lots.

FreePBX seems to be fixing it in their newest version: https://issues.freepbx.org/browse/FREEPBX-15656
