4.0.20 64bit crashes 'out of the box' (segfault as I start it). I just filed a bug report for that > By key-cache, are you referring to the variable "key_buffer_size"? If > so, keep in mind that the key-buffer is for MyISAM, and only caches the > indexes. From, http://dev.mysql.com/doc/mysql/en/MyISAM_key_cache.html yes. I am refering to key_buffer_size. My tables are rather large. The data is log data (one table for each day) and the MYI files are of the order of 2-4 GByte for each day. The intend of setting key_buffer_size to 8 GByte was to keep 2-3 days worth of indexes buffered (the last 2-3 days, which are the most 'popular' for queries). > Your database would have to be huge to have 4 gig worth of indexes. What > if you try to scale it back to 2 gig (or less) and let it run for a few > days? currently trying that out. Its a bit hard to nail this down, as I am still setting things up and the load is low (compared to the production copy). Takes about 5 hrs or so right now for the DB to crash. I did see a bug report related to 'load table from master' with may apply, as I am using this command to populate the database while testing. > Does it generate a core file?

No core file so far. But i managed to get a (very brief) erorr message. All it tells me is that is caught a 'signal 11'.
