Hi, On a Squid server I'm seeing how the buffer mem usage is steadily growing. I'm running out of free memory. top - 08:34:25 up 37 days, 1:00, 2 users, load average: 1.39, 1.27, 1.36 Tasks: 340 total, 1 running, 339 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.6 us, 0.2 sy, 0.0 ni, 97.1 id, 0.0 wa, 0.0 hi, 2.0 si, 0.0 st KiB Mem : 32865056 total, 1290836 free, 2768896 used, 28805324 buff/cache KiB Swap: 37036988 total, 36864784 free, 172204 used. 29598916 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24461 squid 20 0 185632 98884 12724 S 1.3 0.3 0:10.68 squid 24464 squid 20 0 41808 7832 5756 S 1.3 0.0 0:06.82 ssl_crtd 23809 suricata 20 0 2128940 355196 7228 S 0.7 1.1 0:12.19 Suricata-Main 24067 nobody 20 0 67600 13688 6228 S 0.7 0.0 0:00.17 policyd-spf 28110 named 20 0 811544 157968 7308 S 0.7 0.5 95:07.45 named 8000 mysql 20 0 4645052 638484 8300 S 0.3 1.9 377:43.12 mysqld 23645 postfix 23 3 1022224 526076 4284 S 0.3 1.6 0:15.28 clamd 23755 postfix 20 0 201200 83956 10348 S 0.3 0.3 0:02.33 mimedefang.pl 24061 postfix 20 0 146600 11620 9756 S 0.3 0.0 0:00.11 smtpd 24489 squid 20 0 68972 15396 6404 S 0.3 0.0 0:01.34 squid_url_looku 25202 root 20 0 294616 5572 4388 S 0.3 0.0 0:02.29 syslog-ng 27846 root 20 0 20252 2924 2180 R 0.3 0.0 0:00.03 top 27886 root 20 0 221996 8960 6804 S 0.3 0.0 3:43.46 nmbd 1 root 20 0 4176 1588 1508 S 0.0 0.0 0:19.16 init [...] # ps aux --sort -rss | head -n 20 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND mysql 8000 0.7 1.9 4645052 638484 ?

In other words, should I worry or not if the value of "free" (in top) drops that much? I not sure how I'm supposed to interpret the output of the ps commands above. For example, the sum of %MEM is usually between 5 and 10%. Shouldn't this mean that the overall system is not requiring that much RAM? Also, my squid settings are quite modest in that I have this in the conf file: cache_dir diskd /var/cache/squid 32 16 256 cache_mem 32 MB # squidclient mgr:info Squid Object Cache: Version
