      Oleksiy's UPDATE: see command below to understand why this issue is related to escalator, not alerter.

      I have a problem with alerter process. It stuck (not sending e-mails) after 2-3 days of zabbix server working.
      Process itself is working correctly, it is shown on `ps` command:

      7426 ?        S      0:03  \_ /usr/sbin/zabbix_server: alerter [sent alerts: 0 success, 0 fail in 0.000784 sec, idle 30 sec]

      Every 30 seconds it runs:

      7426 ?        S      0:03  \_ /usr/sbin/zabbix_server: alerter [sent alerts: 0 success, 0 fail in 0.000736 sec, idle 30 sec]

      But none of emails are sent. When I kill the process (only one zabbix_server fork) Zabbix will restart it and all old email are send immediately. The same I restart zabbix_server service.
      During the stuck I increase debug for alerter:

      7426:20151212:112149.032 alerter [sending alerts]
 7426:20151212:112149.033 query [txnlev:0] [select a.alertid,a.mediatypeid,a.sendto,a.subject,a.message,a.status,mt.mediatypeid,mt.type,mt.description,mt.smtp_server,mt.smtp_helo,mt.smtp_email,mt.exec_path,mt.gsm_modem,mt.username,mt.passwd,a.retries from alerts a,media_type mt where a.mediatypeid=mt.mediatypeid and a.status=0 and a.alerttype=0 order by a.alertid]
  7426:20151212:112149.034 alerter [sent alerts: 0 success, 0 fail in 0.000906 sec, idle 30 sec]

      I queried the zabbix database with this SQL query, and there is 0 rows returned. But after the fork restarted (or zabbix_server restart) this query returns a lot of rows and emails are send.

      16653 ?        S      0:00  \_ /usr/sbin/zabbix_server: alerter [sending alerts]

      And zabbix server log:
