[asterisk-bugs] [JIRA] (ASTERISK-29367) app_voicemail: reload causes voicemail taskprocessor overload with ODBC and pollmailboxes

[Luke Escude (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=254362#comment-254362 ] 

Luke Escude commented on ASTERISK-29367:
----------------------------------------

So we pushed a change to production that eliminates pollmailboxes (and externnotify) and the taskprocessor overload no longer occurs.

>          Issue Type: Bug
>      Security Level: None
>          Components: Applications/app_voicemail
>    Affects Versions: 16.14.0

> We have the default taskprocessor queue size configured for VM: Low is 450, High is 500.
> We have a higher-volume instance (typically around 35 simul calls at 11am on weekdays) of Asterisk 16.14 that appears to be hitting the high water mark whenever a Core Reload occurs.
> I'm looking around to try and find out what exactly the Voicemail module is doing but I can't find any diagnostic commands to run for you guys.
> There are only like maybe 30 voicemail boxes configured for this system. Additionally, the following parameters in voicemail.conf exist:
> {noformat}
> pollmailboxes=yes
> pollfreq=60
> maxsecs=600
> maxsilence=10
> minsecs=1
> serveremail=no-reply at domain
> attach=yes
> fromstring=From
> emailsubject=New Voicemail
> emailbody=Body
> externnotify=sh /primevox_scripts/voicemail_notify.sh
> externpassnotify=sh /primevox_scripts/update_vm_password.sh
> odbcstorage=vmodbc
> odbctable=vm_table
> {noformat}
> So we're using ODBC for voicemail storage. Newest MariaDB Connector and UnixODBC 2.3.9 compiled.
