Issue ID: 9555 Summary: Introduce a default operations timeout for back-asyncmeta Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: backends Assignee: bugs@openldap.org Reporter: nivanova@symas.com Target Milestone: ---

Currently, if no operation timeout is configured, the default asyncmeta behavior is to have no timeout. This is potentially unsafe - if for some reason a target server does not return a response, the operation will stay in the queue until the connection is reset due to some network error (idle-timeout is not honored if there are pending operations). In the case of many such operations, the queues can get filled up and asyncmeta will become unable to process new operations for some time.

Therefore, a setting of "0" should be used carefully and with intent. To prevent accidental configuration of 0, the default operations timeout should be a value larger than 0.
