We are running CentOS 6.3 with all the latest updates. (Attempt to resolve this issue) The Server I am trying to connect to is a Windows Server 2008 R2 box. Though this applies to our old SBS'03 Box too. I can mount the share, browse it all I want. Copy stuff off of the share and it keeps chugging right along. The issue arrives when my Zimbra server, or any other write operation for that matter, hits the share. It works for a few min takes a fair amount of data, then the share seems to lockup. If I go into Server Manager on the Windows box, find the session and kill it. The drive reconnects and starts working perfectly again. There are no real errors except that Linux starts issuing connection errors
Any Help would be greatly appreciated.
