<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So, I'm definitely a fan of using the busy timeout rather than this arbitrary polling (which, as the comment suggests, is ... not good).
I do think we should be handling the return code from sqlite3_exec here however, rather than simply relying on something being in error:
res = sqlite3_exec(db, sql, NULL, NULL, &error);
if (res != SQLITE_OK) {
ast_log(LOG_ERROR, "%s. SQL: %s.\n", error, sql);
sqlite3_free(error);
}</pre>

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.</pre>
