[OpenSIPS-Users] Failed to replicate Dialog

[Liviu Chircu]

Hello Kneeoh,

Finally managed to replicate these errors on my own setup. In my case, 
the cause was insufficient shared memory for the _primary_ OpenSIPS 
instance, which MAY end up with some missing data within the dialog 
module structures, and unfortunately it gets replicated that way.

Recommendation:
Please make sure you always have enough shared memory ("-m" and "-M" 
command line parameters, or variables from /etc/default/opensips). For 
each 1K calls/sec with tm+dialog and 60s duration you need roughly 640MB 
of shared memory. Regarding pkg memory (-M parameter), just use "-M16" 
and you should be fine.

Best regards,
