As many of you know, the CIS Zimbra service has been “mis-behaving” since roughly 10pm on Tuesday, October 12th.The symptoms of this behavior: poor responsiveness leading to an unresponsive system – typically within 20-30 minutes of last restart.We have a temporary “work-around” in place until Zimbra has a fix for us – we restart the affected process once every 15 minutes. The restart takes around 90 seconds, during which time IMAP and web-based access is unavailable.After doing our own investigation into the issue, we have been working around the clock with Zimbra support on this issue since around 2AM this morning. Zimbra has several developers working on this, and are following several leads. It is at their highest level of priority and we have stressed to them how important it is that we get this solved quickly.As new information becomes available, we will pass it along. Please feel free to contact me directly to address any questions and concerns.Thank you for your continued patience.
At the moment, we’re still waiting for some fix from Zimbra. We’re giving them until Sunday evening before we start trying more drastic measures. We felt this time frame was acceptable given that mail is generally working, except for a 90 second IMAP outage every 15 minutes on the quarter hour.
