Hello,

I'm having an issue with one of our 9 servers that we backup with a central Amanda server. For some reason, this particular mail server becomes unresponsive (all mail services timeout, console unresponsive etc) for about 20 minutes during the backup process. It looks like during that time, the client is doing the indexing step. I have servers with larger partitions and less RAM and they backup without a hitch. The backup does finish successfully from what i can tell, but I can't have this production mail server down for 20 mins each weeknight. Below are the particulars. Please let me know any further info that would help out in troubleshooting this issue.

OS: FreeBSD 7.2-STABLE
