Re: (another?) Not currently OK to rewrite swap log

OK, can anyone estimate for me what size the swap log is likely to be if
there's 8GB of cached objects on that partitiion? Maybe 300K isn't
enough to write the swap log and this is causing the problem. Can anyone
see a way to get objective about this without replacing the RAM at this
stage?

Regards,
