Hi all, I am getting sporadic Xorg / KDE lockups or=20 process crashes. It seems to be related to hitting the=20 kern.maxfiles value. What I am seeing looks like a lot of unclosed file descriptors that are clogging the system badly.=20 FreeBSD 8.0-RELEASE #0: Sat Nov 21 15:48:17 UTC 2009 Xorg 7.5 KDE 3.5.10_7 Firefox 3.6.8,1 I use Kmail to access my dovecot server on another box. Symptoms include messages like unable to cd into /home/me/stuff/next_level Or unable to access a shared lib. If I close konqerer or kamail or firefox, Then it sometimes comes good, other wise the best solution is to logout of=20 KDE / Xorg and (re)startx again. At the command prompt, without Xorg / KDE running I usually see and=20 kern.openfiles value of about 350, It will jump up to about 900 or more on the startx which also launches KDE, that up to arounf 10000, 11000 with=20 Kmail, konqerer and firefox running. It will sometime hover there for days, Then go up and cause freezes, nonstarts etc . Other times it will go up Within a hour or so.... I've looked at tuning(7) and currently kern.maxfiles is set to 24000. I have hald and dbus running for xorg Any udeas ? --=20 Murray Taylor Bytecraft Systems Special Projects Engineer P: +61 3 8710 0600 D: +61 3 9238 4275 F: +61 3 9238 4140 =20|_|0|_| "Absence of evidence =20|_|_|0| is not evidence of absence" =20|0|0|0| Carl Sagan --------------------------------------------------------------- The information transmitted in this e-mail is for the exclusive use of the intended addressee and may contain confidential and/or privileged material.
