Message 4228 - Posted 7 Aug 2008 11:59:33 UTC

Only the feeder is not running but I am unable to upload any work due to this error :--

Server Error: Can't Attach Shared Memory

This error has been going on for at least 6 hours now.

Have also had a couple of computation errors but as I can't find any errors in the messages I will have to wait till I can upload them to find out what the problem was.

Got another couple of the older work units that have been sent back out as resends and gone to well over 5 hours before erroring out, I have aborted a couple of these.

Yes, the feeder has indeed some problems. We are working on this.

Thanks for the note,

For some reason the feeder had lost the connection with the database. We recovered the connection and we are monitoring the feeder in case it happens again.

G'Day Michela,
Thanks for getting things going again.
I have had to abort well over 100 (about 130 I think) work units that have been sent to me.

They were all resends with an original creation date of the 28th and 29th of July.
I noticed that I had started to run some computation errors and work units were running longer than 1.5 hours (up to 5.5 hours) with no progress showing.

This is how all the failed work units ran that I had caught a few days ago.

They all had numbers from 36 to less than 1700. possibly hoarded work units on computers that have not returned the work on time so has been reissued. As it CHARMM 6.04 work that has been redone as CHARMM 6.07 work it will, I believe, always give a computation error.

All now running ok.

Thank you for your note. We restarted the feeder. I think today we will modify it to don't die like that when the connection is lost.

Since three days we have the problem that the feeder suddenly does not connect with the database. I am working on this.

I will keep you posted.
