The upgrade from dcc-1.3.122 (32 bit) to dcc-1.3.125 (64 bit) was flawless. However, we now have a problem with writes from dccd saturating the disk. The I/O bandwidth is often 100% utilized. Other processes that need to read from the disk are stalling. This is Solaris 10 5/09. Neither `-F' nor `-f' are specified in dcc_conf. Can I add `-f' someplace to get memory mapped I/O? Does this have to be specified for dbclean separately? Where's the best place? -- -Gary Mills- -Unix Group- -Computer and Network Services- _______________________________________________ DCC mailing list [email protected] http://www.rhyolite.com/mailman/listinfo/dcc
