Base system is on a geom_mirror, everything else is inside a few ZFS raidz1 pools. Everything except sshd runs inside jails. Three days ago I noticed that my audio/icecast2 (2.3.2, from ports) suddenly stopped processing connections. Couldn't stop it conventionally, either; only kill -9 worked. Then the same day Apache's httpd (2.2.18, prefork, built manually) stopped responding; child processes were stuck in state and never finished, and the dispatcher didn't spawn any new ones. However in this case 'apachectl restart' worked, and defunct processes were successfully killed. With gdb attached to icecast2, I can see 6 threads running, all of them except two being inside nanosleep(). The main process seems to be stuck a= t 453 ret =3D poll(ufds, global.server_sockets, timeout); Step by step execution in gdb inside poll() have somehow unfrozen the process at least once. Any advice on what might be the issue here? There are no issues with the HDDs (or so it seems; nothing in dmesg, and SMART health assessment is "All OK"). I haven't tried to restart the server as it's really unwelcome (and I doubt it's a proper solution). I've also did "make -j8 buildworld" to see if there might be RAM issues (as buildworld usually crashes on faulty RAM). No problems, either. Thanks in advance. P.S. Please CC, I am not subscribed to this list. --=20 Kamigishi Rei KREI-RIPE --------------enig1239FF6E8BEADA4FD48AC763 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iQEVAwUBTTqXkPAgyqbDpP+eAQKmXQf/WarvfFOO33KNccNPKMq85JZPBplrnkEb 9hz0LabdIFa3ZcEwS/+RzNI8d1Mq6zazRiCvprLLdSb4fH5MRfVMDgzsXfO+EdB9 OS9k9LztJRZEYNdcjuScn8ZE3GlpzMeNDjY3AP9iJ4ItpAOHjkaBNR/x6vz1CZXZ jtSoGKiUy5liJCQC4zign8tnHJtbCZPhf0SDySs6jJV0jm7U+1QbY2bYlmb+0ank qVjq7QMB9Pum4Md4SoQtydywsd6Da4nJ9vzgs159UTVXXH58NuQW3kyOC+VS4wvl xmUsBWHNmrnkxzD+X6CWxCVwy6mfRK6fJr+e6ekhiY9E0O3XUk808g== =E++Z -----END PGP SIGNATURE----- --------------enig1239FF6E8BEADA4FD48AC763--
