Description Florence Blanc-Renaud 2018-07-10 05:33:32 UTC

Cloned from upstream: https://pagure.io/freeipa/issue/7605


### Issue
During parallel ipa-replica-install, each replica will connect to the master and send their updates.
There is a good chance that a replica agreement (replica->master) will find the master being BUSY (acquired by an other replica).

This is normal and replica will backoff for sometime. It can lead to ipa-replica-install timeout.

It could be helpfull to reduce nsds5ReplicaReleaseTimeout=10 during that intensive period of parallel install


#### Steps to Reproduce
1. Similar test case of https://pagure.io/freeipa/issue/7595 with 4 replicas parallel install


#### Actual behavior
ipa-replica-install times out

#### Expected behavior
Should not

Comment 5 Florence Blanc-Renaud 2018-11-19 08:21:12 UTC

https://pagure.io/freeipa/issue/7605 was addressed with the fix for https://pagure.io/freeipa/issue/7617. The fix for 7617 was included in 7.6 (BZ 1623112 fixed in ipa-4.6.4-7.el7).

Hence we can close this BZ.
