Subject: [gentoo-security] Apache Mem Usage is driving me nuts
Date: Fri, 14 May 2004 09:46:44
1 Hi,
3 the last few days since my server is hosting a new website the memory
4 usage is givving me serious headaches :(
6 The case:
7 as I said a few days ago I launched a public web-site. after to days the
8 server was like a zombie.
9 With some patience I could manage to get on the server and list what was
10 running. at that time there were a lot of perl script running
11 simultaniously and kjournald was freaking out, well so far so good, as I
12 ran amavis and spamassassin as perl script, so I installed amavis as
13 deamon (amavisd-new) spamassassin integrated,
15 So far everything is ok, amavisd and spamassassin seem to behave nicely,
16 I have less cpu load for mail tasks, but still the problem returns.
18 Looking in the everything log showed me errors like [kernel]
19 __alloc_pages: 0-order allocation failed (gfp=0x1d2/0), seems pretty
20 deadly to me. Well this must be a memory leak or something
21 At that point I started to kill tasks one by one which tasks were not
22 paniced already.
23 MySQLd: this did nothing much to improve the stability
24 Postfix and courier: also no improvement
25 But on killing apache2 the server came back and the command free told
26 me that 500 mb of swap and 350 MB was free-ed.
28 I have looked around how I could strict apache in memory usage for the
29 apache user.
30 What is the best way to prevent that apache takes all memory or maybe
31 exclude a amount of memory for apache?
33 Thanks in advance,
34 Raymond den Ouden
