--4bRzO86E/ozDv8r1 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable In August, I reported that idprio was not working in -current. Successive upgrades to 7.0-BETA2 and 7.0-BETA4, as well as switching to ULE have not resolved the problem. The problem affects both boinc-einsteinathome and boinc-setiathome and causes them to report "No heartbeat from core client for 31 sec - exiting" and get repeatedly restarted. The boinc compute modules (einstein@home, seti@home etc) use a SysV SHM segment to exchange heartbeats with the boinc core client. The problem is that the core client is not being scheduled whilst the compute module is running, causing them to die. Previously, multiple idprio tasks were round-robined but it seems that something has been changed and it appears that the last scheduled task is now re-scheduled. Has anyone else seen this behaviour? --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --4bRzO86E/ozDv8r1 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQFHbikU/opHv/APuIcRAukpAJ0TZxJ73czIGuMir88gwSU4wOykQQCfS0xm 0xLRoAorjYQbTQhWqAK9yGU= =ydtK -----END PGP SIGNATURE----- --4bRzO86E/ozDv8r1--
