I had the same thing on 7-CURRENT with ULE. Looks like the science apps (CPU intensive workers) get bound to cores and starve the boinc-client (the controlling process) out of the picture. Boinc-client should be getting some share of the CPU time. Does not help setting boinc-client to "higher" idprio than the science apps. --=20 Pav Lucistnik It also explains why paper clips just lie there while you look at them, but as soon as you turn your back, they run away, giggling wildly, and transform themselves into coat hangers. --=-8lgBMhdoarxNPBto+X4m Content-Type: application/pgp-signature; name=signature.asc Content-Description: Toto je =?UTF-8?Q?digit=C3=A1ln=C4=9B?= =?ISO-8859-1?Q?_podepsan=E1?= =?UTF-8?Q?_=C4=8D=C3=A1st?= =?ISO-8859-1?Q?_zpr=E1vy?= -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQBHLjNcntdYP8FOsoIRAuFDAKCrZPRt2uob9no5oxyWOdVaUfS4ygCfRru4 RMtEzpwO1aW/weSYjoofrIw= =WmkE -----END PGP SIGNATURE----- --=-8lgBMhdoarxNPBto+X4m--
