There seems to be a race condition when sending SIGHIP to an Icinga process already busy with an ongoing reload. It's pretty easy to reproduce, just launch a few consecutive reloads. You will quickly remain with multiple ido2db childs and therefore be in trouble.

ok, fixed that within the commit for #866 when rewriting the dynamic buffer to a worker thread in ido2db, not blocking the core anymore.

that commit is running in a productive environment by a user, so i consider a bit more cpu usage in the first place a good achievement for fixing this issue and resolving #866
