| high_memory_warning |
If you provide a nonzero value for this directive, Squid periodically checks process size. A large process size can lead to page faults and a significant performance degradation. Squid uses either mstats( ) , mallinfo( ) , or sbrk( ) to get the process size. If it exceeds the given threshold, Squid prints a warning message in cache.log .
