boot error (1 reply)

I'm running 64bit Solaris 10 on a Sparc v445, with 32G memory. I am running mysql v5.5.19 32bit. I am not asking a mysql question but a question about the limitations of processes and memory running on this server.

I have 10G of swap space.

I changed the mysql configuration to allocate 4000M for a memory buffer and it would not start because it said it couldn't allocate the memory. I have plenty free. I tried 3500M and got other errors and it would start. I was able to set it at 3000M and start mysql without problem.

These are the errors at 4000M (4G)
150129 4:04:15 InnoDB: Initializing buffer pool, size = 3.9G
