Oracle Coherence on Solaris 10
In the process of tracing down some performance issues with Oracle Coherence, I ran across the following other possibly-related TODOs.
Sun Alert 102712/201290 Fixed in patch 118833-30+ (sparc), 118855-30+(x86), or add set ip:dohwcksum=0 to /etc/system
Sun Alert 102714/210256 Fixed in patch 118822-21+ and without 125100-10 (sparc), 118844-21+ and without 125101-10 (x86)

Coherence expects a 1500 byte MTU, so default packet size of 1468. Nothing scary there.
