Hi, I run a ejabberd node on an Azure Virtual Machine and I use odbc for most of the funcionalities.
Problem is, after some days, ejabberd loses the connection to the database and it seems it cannot restore it correctly, so I have to restart ejabberd itself manually.
Error:
2016-12-28 16:43:40.084 [error] <0.24869.2>@ejabberd_sql:check_error:1033 SQL query 'Q9525209' at {sql_queries,145} failed: <<"[FreeTDS][SQL Server]Communication link failure SQLSTATE$
I post the configuration down here, hope for some help :)
### ###' ejabberd configuration file ### ###
### The parameters used in this configuration file are explained in more detail ### in the ejabberd Installation and Operation Guide. ### Please consult the Guide in case of doubts, it is included with ### your copy of ejabberd, and is also available online at ### http://www.process-one.net/en/ejabberd/docs/
### The configuration file is written in YAML. ### Refer to http://en.wikipedia.org/wiki/YAML for the brief description. ### However, ejabberd treats different literals as different types: ### ### - unquoted or single-quoted strings. They are called "atoms". ### Example: dog, 'Jupiter', '3.14159', YELLOW ### ### - numeric literals. Example: 3, -45.0, .0 ### ### - quoted or folded strings. ### Examples of quoted string: "Lizzard", "orange". ### Example of folded string: ### > Art thou not Romeo, ### and a Montague?
###. ======= ###' LOGGING
## ## loglevel: Verbosity of log files generated by ejabberd. ## 0: No ejabberd log at all (not recommended) ## 1: Critical ## 2: Error ## 3: Warning ## 4: Info ## 5: Debug ## loglevel: 4
## ## rotation: Describe how to rotate logs. Either size and/or date can trigger ## log rotation. Setting count to N keeps N rotated logs. Setting count to 0 ## does not disable rotation, it instead rotates the file and keeps no previous ## versions around. Setting size to X rotate log when it reaches X bytes. ## To disable rotation set the size to 0 and the date to "" ## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf. ## Some examples: ## $D0 rotate every night at midnight ## $D23 rotate every day at 23:00 hr ## $W0D23 rotate every week on Sunday at 23:00 hr ## $W5D16 rotate every week on Friday at 16:00 hr ## $M1D0 rotate on the first day of every month at midnight ## $M5D6 rotate on every 5th day of the month at 6:00 hr ## log_rotate_size: 10485760 log_rotate_date: "" log_rotate_count: 1
## ## overload protection: If you want to limit the number of messages per second ## allowed from error_logger, which is a good idea if you want to avoid a flood ## of messages when system is overloaded, you can set a limit. ## 100 is ejabberd's default. log_rate_limit: 100
## ## watchdog_admins: Only useful for developers: if an ejabberd process ## consumes a lot of memory, send live notifications to these XMPP ## accounts. ## ## watchdog_admins: ## - "admin@anuserRemoteVM.xny2e1cwaibufevbp43v3ynqjf.ax.internal.cloudapp.net"
###. =============== ###' NODE PARAMETERS
## ## net_ticktime: Specifies net_kernel tick time in seconds. This options must have ## identical value on all nodes, and in most cases shouldn't be changed at all from ## default value. ## ## net_ticktime: 60
###. ================ ###' SERVED HOSTNAMES
## ## hosts: Domains served by ejabberd. ## You can define one or several, for example: ## hosts: ## - "example.net" ## - "example.com" ## - "example.org" ##
## ## route_subdomains: Delegate subdomains to other XMPP servers. ## For example, if this ejabberd serves example.org and you want ## to allow communication with an XMPP server called im.example.org. ## ## route_subdomains: s2s
###. =============== ###' LISTENING PORTS
## ## listen: The ports ejabberd will listen on, which service each is handled ## by and what options to start it with. ## listen: - port: 5222 module: ejabberd_c2s certfile: "/opt/ejabberd-16.06/conf/server.pem" starttls: true ## To enforce TLS encryption for client connections, ## use this instead of the "starttls" option: ## starttls_required: true ## ## Custom OpenSSL options ## protocol_options: - "no_sslv3" ## - "no_tlsv1" max_stanza_size: 65536 shaper: c2s_shaper access: c2s - port: 5269 module: ejabberd_s2s_in max_stanza_size: 131072 shaper: s2s_shaper ## ## ejabberd_service: Interact with external components (transports, ...) ## ## - ## port: 8888 ## module: ejabberd_service ## access: all ## shaper_rule: fast ## ip: "127.0.0.1" ## hosts: ## "icq.example.org": ## password: "secret" ## "sms.example.org": ## password: "secret"
