I use max-requests = 450. After the first request, the process has aprox. 160MB.
After more tests, it seems to have to do with the first requests to an reloaded idle instance. It may be a concurrency problem, e.g. concurrent imports. I think I have captured this situation with strace, but I'm still looking at it. Regards.
