Re: [MirageOS-devel] Memory exhaustion in Mirage



Is it possible to deallocate an Io_page after packet is send, not to wait for GC?

I am wondering if the following issue is already addressed:

It probably still happens at 64MB of RAM -- it requires some code to adjust
the GC parameters in the OCaml runtime to trigger a collection more often.
It should be harmless however, since (as the bug report observes), a failure
to allocate an Io_page results in a GC compaction that frees up memory so
that the allocation eventually succeeds.

Any particular reason for asking -- is the bug affecting your switch somehow?
