Bug #8183
Updated by Ward Vandewege over 8 years ago
A user created over 20,000 groups on one of our installations. For admin users (who can see every group) and for the user in question, Workbench appears to request all of these groups, 100 at a time, for each page load. An example from the api server logs: <pre> ... 10.28.0.7 - - [11/Jan/2016:19:33:58 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53511 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:33:59 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 52721 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:33:59 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53510 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:00 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53510 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:00 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53508 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:00 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53507 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:00 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53512 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:01 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53511 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" 10.28.0.7 - - [11/Jan/2016:19:34:01 +0000] "POST /arvados/v1/groups HTTP/1.1" 200 53506 "-" "HTTPClient/1.0 (2.6.0.1, ruby 2.1.4 (2014-10-27))" ... </pre> This is so slow that it causes the nginx reverse proxy to time out, making workbench unusable. The API server is fine - the cli interface works. out.
