[BUG] Memory leak on the browser's side which crashes the tab #410

Open Monniasza opened 2 weeks ago

Monniasza commented 2 weeks ago

Hi. I've seen that leaving the mapserver running on a busy server causes a memory leak that crashes the tab after about 1 hour from the load.

To reproduce:

I expected the mapserver to run indefinitely

The system has about 16 GB of RAM.
