I did a number of changes that may impact stability recently. It would help if you provide more details like: =2D release/architecture tuple =2D PORTREVISION =2D selected options (all or against default) =2D gtk and glib version installed =2D which plugins are installed =2D graphics and plugin/ipc stuff from about:support=20 =2D whether sdt.ko (dtrace) is loaded =2D whether dbus and pulseaudio daemons are running > > Is there a trace/debugging hint that helps you and the gecko team > to debug this ? Try $ procstat -k $(pgrep firefox) $ ktrace firefox -no-remote -profile $(mktemp -d) <wait for hang> ^C $ kdump -R | tail -20 $ lldb -p $(pgrep firefox) (lldb) bt all If it's busy wait $ kldload hwpmc $ pmcstat -t firefox -P instructions -T (the rest I don't remember ;) =2D- To get useful stacktraces build with STRIP=3D (empty) in make.conf or enable one of DEBUG, DTRACE, PROFILE options. Beware, DEBUG builds may have a set of their own issues. Library dependencies need to be rebuilt with at least non-debug symbols as well. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQF8BAEBCgBmBQJW5aUnXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXREQjQ0MzY3NEM3RDIzNTc4NkUxNDkyQ0VF NEM3Nzg4MzQ3OURCRERCAAoJEOTHeINHnb3bLtMH/1RNs4vSzD66hB/9LfNL7zWK 7jDEPbJ1YRN8aIhGKDOFpPM4aJVN44Np8a7PmgPQKO9PAErLdiwqVNXYyAECRNor Rjv3Kfg1xkwKdkme7ZhCBUsYgdzaUFkYc+AjfFT88PBeE6B4XGCBbcq1x4feZmfG wrmyFGjsCEd8d4ZS85xgKUg3rW48p2vUnIs70VhEKz6gP2aPJoinq5plau5iBGSh 5mvLoJvT7TLOq+wenwT9NcNCK7XADHgcwIj4kL/UL6Dz30hCvU3VzEO/IiWjpMj5 rLXlDFoHERQ12hfxV6YiF0OXE74HprkkflmwKf089t2520+I7XCiUi9Wxd02w2k= =tZc+ -----END PGP SIGNATURE----- --=-=-=--
