You could provide some more information: - How much memory does your machine have, how much is actually available for apache (i.e. not used by other processes). - Which MPM do you use? - What are your settings for StartServers, MaxRequestsPerChild, ThreadsPerChild, MinSpareThreads/MinSpareServers, MaxSpareThreads/MaxSpareServers - How large do the apache2 processes grow? (RSS) How quickly do they grow? - How many apache2 are running during normal operation? Tune the above settings. If processes grow slowly, you may be hitting a memory leak. Setting MaxRequestsPerChild to non-zero (e.g. to 500) may help. If that doesn't help, try setting 'MaxMemFree 4'. If that doesn't help enough, add 'export MALLOC_MMAP_THRESHOLD_=8000' to /etc/apache2/envvars (the trailing underscore is not a typo). These options lower performance, though. Please report back about the results. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
