Many thanks to Casper Dik, Rich Teer, and especially Michael Schulte for reminding me of some simple arithmetic. My question (paraphrased): My group has an E6500 server running Solaris 2.6 with the shmmax kernel parameter set to 6 GB. The system boots and is running just fine; however, sysdef reports that shmmax is set to 2GB. I wanted to know if this would / could cause problems other than performance degradation, and I also was curious as to how the OS arrived at 2GB. Basic answers: Shouldn't be an issue with the system (and we'll fix it next time we get a chance). With regards to the 2 GB value, the system apparently chopped off the high-order bit. 6 GB = 2^32 + 2^31, after shifting the high-order bit you get 2^31 = 2 GB. I knew I was missing something simple.
