I don't see what pmap should have to do with socket buffers. Socket buffers would live in the kernel, I think, not in user space (which is what pmap shows). If pmap shows space growing, I'd think it's either in your code or in a library. You don't say what version of [Open]Solaris you're using, which may make it harder to point you to any known bug... -- This message posted from opensolaris.org
