We are running Exchange 2010 Enterprise on a 2008 R2 Enterprise server. This server is our mail server, web server, file server, ftp server, etc.
Every few days, for some reason, I see a very large number of logfiles for our primary Exchange database. In one day, I had over 30,000 log files. Normally there are far fewer logfiles at the end of the day, usually closer to 1,000.
We backup Exchange every night which clears out the log files from the previous day.
I noticed today when I saw around 10 logfiles being generated per minute that if I restarted the DNS server service, Exchange stopped creating logfiles at such a fast pace. I have seen this happen several times bfore.
Anyone have an idea of what is happening? I can't find any error messages that would give me a clue.
