I have the same problem on two systems here: periodically the systems will stop dead (no mouse action, no ping responses from other systems, processes with windows on the screen also freeze); the hangs can be anything from a few seconds to several MINUTES; then it all comes back "as if nothing happened" except that keyboard input during the freeze is lost. Most of my freezes are a few seconds long, some are in the 15-60 second range, but (fortunately, rarely) I have seen some that lasted 10-15 MINUTES! The only obvious indication after the return is that the system load average monitor peaks up, typically from the 0-0.5 range before the hang to 1.5-2 after the hang, then immediately decays back down. Just as if some real-time prio process had grabbed the processor exclusively for a while. Except I have no rtprio processes that I know of. It is not swap related. One of the systems here has 4GB ram and is not swapping, even after one of these freezes. It doesn't even swap while running X, with the mailer open, several xterms and firefox and a make running. I had not reported this because I figured this was yet another problem with xorg-7.3. I am unable to make it happen on demand. As yet it seems random. I am able to do CPU-intensive stuff (e.g., port builds) without problems: it doesn't trigger the freeze and I don't even see the jerky mouse problem that folk also talk of. I am running a make right now in fact, just to see if it'll do it. Of course, it's fine. But the phone might ring, so I'll stop doing things, the system will become pretty-much idle, then I'll go to move the mouse and it might be frozen. When it comes back, the small load peak shows, but top and ps show nothing unusual. As I said, I have two systems here which exhibit this. Both systems here are 7.0BETA4. Different i386 hardware; both are UP systems; one is a fast 3200Ghz processor with 4GB ram, the other is a very slow processor with not much ram at all; the scheduler is SCHED_ULE on both; and the app mix includes basic servers: /usr/sbin/wpa_supplicant dhclient /sbin/devd /usr/sbin/syslogd /usr/local/sbin/cupsd /usr/sbin/ntpd /usr/sbin/powerd /usr/sbin/sshd sendmail /usr/sbin/cron /usr/sbin/moused /usr/local/bin/xdm (on the fast system only) /usr/local/bin/X and various end-user clients such as a WM and its children (including load graph and a clock), firefox, xterms, ical, nvi, etc. Because it is unpredictable, I don't have any profiling of this for you. But I wanted to throw this out there since I am not sure the problem is 6.x-related. Oh, both systems ran 6.2-stable with xorg-6.9 and didn't have this problem. Also, there doesn't seem to be any indication of hardware issues on either. -jr --Sig_/56Sr=gxrz17xMhrLrp8yBMj Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFHhR4jls33urr0k4kRAvGiAKCPyJpCXtScVy+n0oF7dG6gLjXDwQCgiSkR gCXvEfvLboGgSNn2UyZi/Qw= =Y8+H -----END PGP SIGNATURE----- --Sig_/56Sr=gxrz17xMhrLrp8yBMj--
