Hello For nearly 3 years, we have had a master - slaves configuration working like a charm, the slaves would be able to sync daily ... since a recent upgrade from Solaris10u6 to solaris 10 u9 with the latest CPU bundle (kernel patch 147440-19) on one of the two slaves, the slave upgrade cannot keep up anymore... it is now at over 2 days behind in replication and the delay increases... the volume of data did not increase and the second slave seems in good shape (still on u6). No configuration change was done to the mysql configuration itself... Is there a well know issue/parameter to configure with the more recent versions of solaris ? The storage is on an Hitachi san storage with 4Gig HBAs and the volume of data to replicate is about 6-8 1G binary log files a day... Another change is that the new machine global zone is using zfs for the boot disks, but the database zone itself including the data directory is sitting on ufs filesystems... Regards
