Apparently they are timeouts
Apparently they are timeouts when looking information in the MAM table, when different users login. It seems the MAM service cannot handle the amount of requests you send.
How to fix it?
I guess disable mod_mam, or improve its source code efficiency, or restrict your clients to be less aggresive regarding MAM, or improve the machine capabilities (I don't know if the bottleneck is the CPU, RAM or disk).
thanks. if I disable always
thanks. if I disable always and enable roster, will it help me(performance)?
roster's option need query (select) before insert to archive table, which one is better roster or always(performance)?
mod_mam:default: always
cache_size: 1000
cache_life_time: 3600
or
mod_mam:default: roster
cache_size: 1000
cache_life_time: 3600
