В компании происходит переход на одноранговую сеть, т.к. не хватает специалистов понимающих Unix системы. Передо мной стала задача миграции с FreeBSD сервер jabberd 1.4 на Windows 2003 сервер взял ejabberd 2.1.6. Пока решил использовать mnesia базу (на sql всегда будет время еще перейти). Сконфигурировал стандартно, без доп. модулей, все из коробочки инсталлятора. Импортул xml-ки контактов (примерно 800 аккаунтов), погонял с десятком подключенных, работает. Сделал подмену рабочего сервера. Сервер проработал минут 30 и упал.

ets: 444799312До падения из процессов видим, что erl.exe поедает очень много памяти (~1.2Gb).
Решение
32-битная архитектура x86 процессора ограничивает производительность приложений, работающих с большими объёмами данных (x86-64 нет под рукой), а у Erlang на таких системах где-то есть придел ~2Gb, посему получали падение. Проблема решилась переходом на MySQL, за одно и ростеры пользователе почистили, где был хаос. Огорчает одно, что в природе нет mod_shared_roster_odbc

Maybe you found several different problems. For the ERROR REPORT I have created this ticket, because I think it's a bug in ejabberd:
