for all those backlogged results.

|We are currently working on getting the alpha/beta projects working again, as well
as getting new workunits generated so that when we restart the public SETI@home project
there will be work to send out to the clients.

afternoon we encountered a sudden raid failure that caused some data

|Currently the project is up, as we were unable to recreate the
problems we were seeing on Friday

|Today we are continuing to work with Snap technical support to
solve our mounting problems
||1||SETI News||5108||16 Aug 2004|
|We encourage everyone to run SETI@home Classic
during our server outages.
SETI@home Classic makes the same scientific contribution

|All the data has been copied to the Snap device
||1||SETI News||5539||13 Aug 2004|
|The download directory is fully transferred at this point, but we
are still waiting for the upload directory to finish
||1||SETI News||5182||12 Aug 2004|
|The DB is now on the Snap Appliance and the web site is back up.
The project itself is still down as the transfer of the upload and
download directories is still under way.

|The project is now down for the move of the DB and the upload
directory to the Snap Appliance

|A misconfigured scheduling server ran for about an hour this morning,
misinforming users that they had to upgrade to version 4 of the

|We discovered that the sheer number of files in the upload directory
was killing NFS performance for the file_upload_handler
||1||SETI News||5746||4 Aug 2004|
|While the project is up and functioning normally, the database and
web servers are overloaded
||1||SETI News||4788||3 Aug 2004|
|The project remained down all weekend, but we are back up now.
To add insult to injury, the entire lab lost network connectivity
to the rest of the world for a few hours this morning.
In light of the unexpected length of this las

|The project is down while we deal with a backup problem
||1||SETI News||4880||25 Jul 2004|
|The good news is that the scheduler is now running as a fast cgi
which means it maintains a persistent connection to the DB
||1||SETI News||5539||23 Jul 2004|
|We are now up and running again, during the night we generated 400k
results to be sent out
||1||SETI News||5077||23 Jul 2004|

|Sometime between 5pm and 12am PDT, the splitters seem to have
stopped producing new workunits
||1||SETI News||5180||19 Jul 2004|
|A server bug was preventing
new results from being created in response to failed results.
If 2 out of 3 results for a WU succeeded and the 3rd failed,
the 2 successful results would not be validated or credited.
This is no

|Our database server hung and had to be forcibly terminated.
It took several hours to check all the tables and indices.
Then we ran into problems with our
Network Attached Storage device, which we rebooted
for the first tim
||1||SETI News||5616||13 Jul 2004|
|It looks as though the server components
(splitter, transitioner, feeder, scheduler)
are now keeping up with demand.

|Since yesterday evening we have distributed over
||1||SETI News||6070||8 Jul 2004|

order to free up CPU and memory for the DB server
||1||SETI News||5234||8 Jul 2004|

server performance problems.
The project will be shut down for several hours today.
||1||SETI News||5356||7 Jul 2004|

|We've been having problems with server performance.
To address these problems we're making some changes to our database.
The project will be shut down most of today while this is being done.
||1||SETI News||6042||2 Jul 2004|
|Yesterday morning we shut down the front end of the system
to let the transitioners catch up with several days worth
of backlogged work, which is why some of you were noticing
three results and no credit assignment
||1||SETI News||5704||30 Jun 2004|
|The web site has been reenabled.
We have several upgrades scheduled throughout
the week which should help with the performance problems.
If the project runs out of work again you are welcome to
revert back to the original

|We passed the safe threshold again,
so the web site has been shut down until Monday,

||1||SETI News||5293||27 Jun 2004|
|An additional transitioner has been brought online.
We are turning on the web site and will be monitoring the system.
We may have to shut it down again if traffic becomes too bad.
We are investigating further performance enhanceme

|We are going to leave the project down until Monday.

|We added a second splitter and then hit the next bottleneck which
was the transitioner.
||1||SETI News||5159||25 Jun 2004|
|Memory for our web server was defective;
