Memory leak? #18

Closed devasmith closed 1 year ago

devasmith commented 1 year ago

Hi. We are using coraza-spoa which is using this library. Notices that this service is gradually increasing it's memory usage. This service is now enabled on a site that has a lot of incoming requests to process.

Took out a pprof file and a graph of the memory consumption.

Together with this memory usage we notice this: level=warning msg="spoe: error handling connection: disconnect error: I/O error"

Not sure if this is connected to haproxy-spoe-go or something else but that causes a lot of the requests to not be processed correctly (Failed to parse request body).

Any clue on how we can troubleshoot this further?
