Functional Test 5 Aug 2008

There were many errors observed between 14h10 - 14h40.

[SOURCE error during PREPARATION phase: [REQUEST_TIMEOUT] failed to prepare source file in 180 seconds] Source Host [ccsrm.in2p3.fr]

• A similar effect was observed also in CCRC08, but it was difficult to summarize at the time.

The files were transferred successfully in the end, but before the successfull transfers, there were many attempts with the error.

From the graphs below;

• the first 10 minutes: many transfers fail and few succeed
• the next 20 minutes: still many transfers fail but success rate increases
• the next 10 minutes: less failure rate with less transfers (most of the files have been transferred)

• 15 errors for RO-02-NIPNE_DATADISK [10]
• 6 errors for RO-07-NIPNE_DATADISK [11]
• RO-07-NIPNE was in downtime[12], therefore zero success. But we still see this type of error in source preparation.
• GRIF-LPNHE was in downtime [13] and FTS channel was active, therefore many destination errors. (zero success rate)
• TOKYO was in downtime [14] and FTS channel was inactive, therefore no transfers.

• Total 242 errors of this type between 12h00 - 16h00, mostly between 14h00-15h00.

• there seem to be some inconsistency in the dashboard information. Thus the above numbers may not be exact.
