#47374: unison freezes entire machine
----------------------+--------------------------------
Reporter: geezel@… | Owner: macports-tickets@…
Type: defect | Status: new
Priority: Normal | Milestone:
Component: ports | Version: 2.3.3
Keywords: freeze | Port: unison
----------------------+--------------------------------
Running unison on a single folder with only a few (about 50) large files
freezes the entire machine.
Unison itself does not crash or display an error message, but it consumes
more and more memory until
the machine reboots. Other processes also become unresponsive, i.e. once
the unison command
is launched there is no way to recover.
For reasons discussed in this ticket
https://trac.macports.org/ticket/45621 this has been tested
with various versions (unison 2.40.102 compiled against ocaml 4.01 and
4.02, and unison 2.48.3
against ocaml 4.01). They all exhibit the same behaviour.
Unison on FreeBSD runs fine on the same set of files (all versions). Also,
a temporary workaround on
Mac OS X is to run unison with the option "copythreshold = 1024", which
makes unison use rsync
to transfer large files.
This might well be an upstream bug. If anybody is able to confirm this
behaviour I'd be willing to report
it upstream.
