Mailing list mail delayed over the weekend

by

The department’s mailing list server ran out of disk space late Friday, April 26, around 4:30pm. A single very large message to one list caused what should have been a temporary issue. I removed some unnecessary files on Friday and thought that everything was working normally, but this morning noticed messages were not being distributed.

The server was restarted and has since caught up with all outstanding messages. Because of this you may notice messages sent over the last 3 days just showing up in your mailbox today, but no mail has been lost.

An investigation is underway as to why our old monitoring software did not alert us to this problem sooner. A new monitoring solution is being deployed in IRIS and this server will be moved to this new monitoring solution as soon as possible.

Third Unplanned Power Outage to 165 Cory

by

Report from Scott McNally:

“Power was just lost again at 3:40pm Wednesday, 4/10/13. We will have to triage the number of machines we allow on in this room once we restore power. Then we still have a power shutdown on Friday to replace the faulty breaker.”

Mailed earlier today to the Cory Sysadmins maillist:

“Campus is planning a shutdown of Electrical Services to Computer Machine Room 165 and the East Side 1st floor of Cory Hall on Friday, 4/12/2013, between the hours of 9am-Noon to replace the faulty breaker. We are currently operating critical equipment only in room 165. In fact we insist no additional equipment be turned back on at this time until after the repairs on Friday can be made. If you are able to shut down equipment that may not be needed between now and Friday, we ask that you do so.”

Web and mailing list server patching, Apr 10 at 7am

by

The department’s web server (www.eecs, www.cs), mailing list server (lists.eecs), wiki server (wiki.eecs), application server (apps.eecs) and jabber server (jabber.eecs) will be restarted Wednesday, April 10 at 7am.

On Tuesday evening these servers will have operating system patches installed which require a restart. They will be restarted automatically at 7am Wednesday morning and should be back in service by 7:15am.

These servers will now be patched (and rebooted if necessary) on the morning following first Tuesday of each month, the same schedule as our Windows servers.

Mailing List Server maintenance

by

The EECS Mailing List Server (lists.eecs.berkeley.edu) will be down for maintenance tonight (Tuesday, Oct 2) between 6pm and 7pm.

The web interface at https://lists.eecs.berkeley.edu may be sporadically unavailable during this time.

Incoming mail to lists.eecs may be delayed during this time. All mail will be delivered after service resumes, but how long it will be delayed depends on how frequently the originating mail server retries. This is typically an hour at most.

Web, Mailing List, Jabber outage May 9th, 6am

by

Due to a major reorganization in the IRIS Data Center, numerous IRIS services will be unavailable 6am-8am, Wednesday May 9.

The servers that support the department’s website, the IRIS website, jabber, ACG applications, the print spooler, the Windows Terminal Server, and the department’s mailing lists will all be physically moved to new locations. Extensive prep work has been done to minimize downtime to the absolute minimum, and we hope that most services will be up sooner, but we are allotting 2 hours for this work.

Mailing List Messages Delayed, Sep 2

by

Beginning around midnight on September 2, our MySQL database server began refusing connections from lists.eecs.berkeley.edu. Since all subscription information is kept in the database, no mailing list messages could be delivered during that time. The database server was reset around 9:30am and all queued departmental email has been delivered at this time (10am). No email should have been lost.

Initial investigation points to the database server intentionally blocking connections due to too many simultaneous requests from lists.eecs. This investigation will continue and the database server will be tuned as needed to prevent a recurrence of this problem.
