La mia macchina consuma tutta la CPU per una o due ore durante l'elaborazione di alcune systemstats. Finora ho risolto il problema pulendo regolarmente l'enorme quantità di dati in /private/var/db/systemstats/
Ora ho notato che ottengo tonnellate di file .stats creati in /var/log/com.apple.launchd.peruser.94 . Un nuovo file viene creato circa ogni 20 secondi. Un elenco assomiglia a questo:
bash-3.2# ls -lt
total 136

Che cosa sta causando questo?
Utilizzo Mavericks 10.9.5 con OSX Server 3.1.2.
EDIT:
L'esecuzione di questo ps -u _teamsserver produce questo risultato:

A volte appare un'altra linea che corrisponde all'intervallo di 20 secondi:

EDIT:
Ho iniziato launchctl e ho esaminato alcuni comandi e output. Il comando list ha mostrato questo:
...
263 - 0x7f96d2d27200.anonymous.pg_receivexlog
258 - 0x7f96d2c68620.anonymous.Python
- 0 com.apple.launchd.peruser.94
215 - 0x7f96d2d19890.anonymous.postgres_real
216 - 0x7f96d2d194c0.anonymous.pg_receivexlog
...
L'elenco della voce peruser.94 più volte fornisce questo: (una volta con una voce PID, una volta non)
launchd% list com.apple.launchd.peruser.94
{
"Label" = "com.apple.launchd.peruser.94";
"LimitLoadToSessionType" = "System";
"OnDemand" = true;
"LastExitStatus" = 0;
"TimeOut" = 30;
"Program" = "/sbin/launchd";
"EnableTransactions" = true;
"MachServices" = {
"com.apple.launchd.peruser.94" = mach-port-object;
};
};
launchd% list com.apple.launchd.peruser.94
{
"Label" = "com.apple.launchd.peruser.94";
"LimitLoadToSessionType" = "System";
"OnDemand" = true;
"LastExitStatus" = 0;
"PID" = 45918;
"TimeOut" = 30;
"Program" = "/sbin/launchd";
"EnableTransactions" = true;
"MachServices" = {
"com.apple.launchd.peruser.94" = mach-port-object;
};
};
Suppongo che dovrei essere in grado di seguire il percorso lungo "MachServices" ecc. Passerò un po 'di tempo a cercare nella documentazione. Qualcuno può darmi qualche suggerimento su dove questo potrebbe portare? Come posso scoprire cosa questo cerca di fare?

Ho cercato tutte le voci in /Applications/Server.app/Contents/ServerRoot/System/Library/LaunchDaemons che contengono "_teamsserver":
