[erlang-questions] VM leaking memory

[Frank Muller]

Hi John

I’ve a process which does that. Every 5mn it checks it the total memory
went above a threshold and I it triggers a garbage collection. But this
time it didn’t help.

My app is a proxy server which forward packets from left to right by
applying a transformation to them on the fly.

That’s not a lot to go on. FWIW, most of my memory issues have been caused
