Looks like we are having file transfer problems again. I'm getting the same HTTP errors as described above. On attempting retries, some complete the download and some fail. Both upload and download files are being impacted

Another night, another set of upload/download issues....
----------------------------------------Getting to be monotonous.... Seems to always happen after the 0000 UTC stats run.... Is the server running out of sockets? [Edit 1 times, last edit by Doneske at Mar 1, 2017 3:54:35 AM] |

Doneske,
I got alerts last night about the server having issues near the 0500-0600 UTC time. When I reviewed the server, I did not notice anything that was scheduled to run during that time on the machine and the logs do not point to anything specific. I have refreshed the server that was struggling in hopes it clears something. We are still working on a root cause. Thanks, -Uplinger |

It seemed to start about 8:45 PM CDT (0245 UTC) and I was still getting HTTP errors at 1:15AM CDT (0715). Then the errors ended. This was happening on all 19 machines and, just as before, some transfers would be successful and some wouldn't be. It looks like an attempt is made to transfer (upload or download) and sometimes a connection is made and sometimes not.
----------------------------------------It just seems suspicious that the system runs all day with few or no errors, at least on my machines, and then right after the 0000 UTC stats activity, we start getting these upload/download errors. Another thing I've noticed in the past is the Website runs slightly slower after the stats for a period of time. It may not be the Webserver itself but maybe the back end pieces it connects to in order to display data like the DB maybe. IT just feels like something is happening on the infrastructure right after the stats process. If all the network sockets are in use when the attempt to transfer happens, it would get an error. Not knowing how the server piece is configured, you may have stated that BOINC could handle 1000 connections but the underlying UNIX networking is only configured to handle 512 max socket connections in the TCPIP configuration. The most connections would be limited to 512 and that probably wouldn't show up in the BOINC logs but might show in the UNIX syslog. Maybe not. All this is just guessing on my part...

I'm not having problems with the upload or download process but I notice that the User totals and averages do not update. Also that Free-DC and BAM stats seem to have got woefully behind.
