While upgrading CMJ, UPM disables and enables Atlassian packages causing downtime to DC instances. Configuration manager has dependent plugins which need to be stopped during the upgrade. But UPM disables all the dependent apps.
Due to its integration with Configuration Manager for Jira (CMJ), Insight Plugin imports dynamically com.botronsoft.cmj.spi.* from CMJ SPI-Bundle. Thus, Insight Plugin gets restarted upon uninstalling/disabling CMJ. Moreover, all core system plugins that depend on Insight Plugin are restarted due to the restart of Insight Plugin causing problems in using core system functionalities as a result.
likely more people will experience this that are on Jira 8.19 with JSM 4.19 or above. identified that the problem seems to be caused by the integration of Insight with CMJ via the SPI.
As mentioned in the following ticket https://jira.atlassian.com/browse/JRASERVER-73869
As of Jira 8.19.0 onward disabling/uninstalling Configuration Manager Core Bundle ( installed with Configuration Manager for Jira app v. 6.10.5 and previous versions)
or
disabling/uninstalling Configuration Manager for Jira SPI Bundle ( installed with
Configuration Manager for Jira up to v. 6.10.6). Results in the largely increased number of dependent plugins to be disabled/re-enabled.
Expected Results
When uninstalling/disabling a given plugin (root plugin), the list of dependent plugins to be disabled/re-enabled is limited to those that require the root plugin
Actual Results
When uninstalling/disabling a given plugin (root plugin), the list of dependent plugins to be disabled/re-enabled includes also many transient dependencies that do not require the root plugin
Workaround
Dependent plugins, have to be enabled manually from "Manage Apps".
