Re: [MirageOS-devel] Memory exhaustion in Mirage



Yes, I have faced this problem several times when flooding the input port (similar error on the console). The allocated memory for the switch is 2GB, which is much higher than 64MB, but I guess bit rate should be higher too.

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?
