Nahodne zabijeni procesu apache

[Martin Stachura]

Dobrý den,

stava se mi, ze na serverech s FreeBSD 12.3 mi system zabiji procesy 
apache a apache je neumi znovu vytvorit. Parkrat se mi stalo, ze system 
postupne zabil vsechny procesy apache (hlavni proces pod root nezabil) a 
tedy apache takovy bezel, ale nebyl zadny proces co by mohl 
vzit/zpracovat pozadavky a web byl nedostupny. V logu pri zapnutem debug 
mi to zadnou poradnou hlasku nevygeneruje. Nestava se mi to pouze na 
jednom serveru, ale na vsech serverech pod FreeBSD s Apache, jenom mi to 
pripadne vypisuje jiny kill kod (10 a 11). Muzete me prosim navest, jak 
muzu debugovat, nalezt pricinu a vyresit tyto problemy. Dekuji.
