I installed rabbitmq on ubuntu 20.04 but when I want start it i get the following result

Job for rabbitmq-server.service failed because the control process exited with error code.
See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.

and when i run service rabbitmq-server status I get following result

There may be some better information in `/var/log/syslog` to explain the failure

Crashes like this are considered a bug. File a bug report with rabbitmq, and attach the dump file to the bug report.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
