On a dev server I have had over the past few days very frequent log switches (as many as 200 per hour), plus "thread 1 cannot allocate new log" and "Checkpoint not complete" errors every few minutes. I had 3 50MB log files. Yesterday I upped to 3 256MB files, and the problem persists. I added one more 256MB, no luck. Log switches of course have dropped to 15-20 per hour which is still too high but not that extreme. "Checkpoint not complete" errors have almost disappeared but "thread 1 cannot allocate new log" errors persist. The system has 8 CPU threads (quad-core i7) and one DB writer as given by the cores/8 rule. Should I add one more DB writer? As this is a dev server it has a SATA drive which of course cannot support high throughput. Thanks for any advice!
