[asterisk-bugs] [JIRA] (ASTERISK-20496) Patch to app_voicemail.c for large vmblasts

[Bob Roswell (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-20496?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bob Roswell updated ASTERISK-20496:
-----------------------------------

    Description: 
Sending Voice Mail Blast to large number (>150) of users crushes system performance.  Calls get dropped, go unanswered etc.  Load Average goes from 0.1 to over 20.

I found that adding a sleep(2) in the routine copy_message fixed my issue.

I added just before return 




Additional information:

1)  Calling VMBLAST from standard FreePBX implementation
2)  Should be patched even though there are workarounds.  All the API's should work.
3)  Found that I had to add a dummy mailbox.  Staggering the voicemails creates a new problem.  If the first person deletes the voicemail, later people in the chain do not get it since code inserts voicemail into first person's box, and then copies from there.
