From a1e0a5e4b07387bcc59afa7c0ab9f960a389ac15 Mon Sep 17 00:00:00 2001 From: Igor Goncharovskiy Date: Mon, 16 Jun 2014 09:04:05 +0000 Subject: We have faced situation when using CDR and CEL by sqlite3 modules. With system having high load (~100 concurrent calls created by sipp) we found many cdr and cel records missed. There is special finction in sqlite3, that make able to fix this situation - sqlite3_wait_timeout, that also can replace awful code cdr_sqlite3 ad cel_sqlite3 modules. Also this function can be used for aastdb and res_config_sqlite3 to avoid missed writes to sqlite db. #ASTERISK-23766 #close Reported by: Igor Goncharovsky Review: https://reviewboard.asterisk.org/r/3559/ ........
