During recent load testing of a new application
3.1% to 7.6% of all http requests resulted in conflict errors
(3.1% with 10 simultaneous users; 7.6% with 50 simultaneous users). The conflict error occurs when the application
attempts to write a small image object into a temporary folder, and each
conflict error generates the same traceback:
Traceback (innermost last): Module Zope2.App.startup, line 173, in zpublisher_exception_hook Module ZPublisher.Publish, line 121, in publish Module Zope2.App.startup, line 240, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 380, in commit Module transaction._transaction, line 378, in commit Module transaction._transaction, line 433, in _commitResources Module ZODB.Connection, line 484, in commit Module ZODB.Connection, line 518, in _commit ConflictError: database conflict error (oid 0x07, class Products.TemporaryFolder.TemporaryFolder.SimpleTemporaryContainer) I am running Zope 2.9.2 on CentOS 4.3 (linux).
Does anyone have any ideas as to what I could do to reduce/eliminate these
conflict errors?
Thanks,
Jonathan |
