[asterisk-bugs] [JIRA] (ASTERISK-29367) Core Reload causes voicemail taskprocessor overload

[Luke Escude (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=254307#comment-254307 ] 

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

Hmm I am noticing something added to Asterisk 17 (and also 18):

`A new module "res_mwi_devstate" has been added that allows subscriptions to voicemail boxes using "presence" events.  This allows common BLF keys to act as voicemail waiting indicators.`


The thing is, we're already able to perform that functionality in 16 using Hints. Is it possible we're doing something drastically incorrect with Hints to cause MWI handling to become overtaxed?

> 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.
