FreeSWITCH may not be responding to requests on port 8021

Question

• I'm getting below error while restarting the BigBlueButton server:

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

# Potential problems described below
grep: /opt/freeswitch/var/log/freeswitch/freeswitch.log: No such file or directory

#
# Error: Unable to connect to the FreeSWITCH Event Socket Layer on port 8021
#

• First, I thought the DB files for freeswitch got corrupted so performed below setps to resolve it (As mentioned in BBB docs):

$ sudo systemctl stop freeswitch 
$ rm -rf /opt/freeswitch/var/lib/freeswitch/db/* 
$ sudo systemctl start freeswitch

• But FreeSWITCH is not creating the new DB files on startup.

• The output of **$/opt/freeswitch/bin#./freeswitch** is as per below:

Answer 1

you can see what the error is just from the log you posted here, the cause is that something wrong with your db file.

Please check

1. if the file exists
2. if the file is corrupted
3. if the file owns the proper permissions.
