[CentOS] Memory Leak with stock Squirrelmail, PHP, mysql, apache since 5.3
Hi list, We are experiencing a memory leak on our SquirrelMail server since the 5.3 update. The server is fully updated, only stock rpms. The httpd processes are eating all the memory and after swapping like hell, the server became unresponsive and we must hard-reboot it. The server is not that much loaded (max 10-15 concurrent users but with tons of mail in their inbox). Configuration's speaking, nothing was changed before and after the update. Is there someone else experiencing the same thing ? How can I search deeper the origin of the leak ? Thx, kfx Details follows: Screenshot from munin showing the memory usage's graph: http://uppix.net/e/a/7/cd2bdea933d57b0e28bde1f96b854.png [root at webmail ~]# uname -a Linux webmail 2.6.18-128.1.6.el5xen #1 SMP Wed Apr 1 09:53:14 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux [root at webmail ~]# yum list | grep -e php -e squirrel -e mysql -e httpd | grep installed httpd.x86_64 2.2.3-22.el5.centos installed mysql.x86_64 5.0.45-7.el5 installed mysql-server.x86_64 5.0.45-7.el5 installed php.x86_64 5.1.6-23.el5 installed php-cli.x86_64 5.1.6-23.el5 installed php-common.x86_64 5.1.6-23.el5 installed php-ldap.x86_64 5.1.6-23.el5 installed php-mbstring.x86_64 5.1.6-23.el5 installed php-mysql.x86_64 5.1.6-23.el5 installed php-pdo.x86_64 5.1.6-23.el5 installed php-pear.noarch 1:1.4.9-4.el5.1 installed php-pear-DB.noarch 1.7.13-1.el5.centos installed php-pear-MDB2.noarch 2.4.1-2.el5.centos installed php-pear-MDB2-Driver-mysql.noarch 1.4.1-3.el5.centos installed squirrelmail.noarch 1.4.8-5.el5.centos.3 installed Dmesg: Apr 2 17:18:28 s_local at webmail kernel:init invoked oom-killer: gfp_mask=0x201d2, order=0, oomkilladj=0 Apr 2 17:18:28 s_local at webmail kernel: Apr 2 17:18:28 s_local at webmail kernel:Call Trace: Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff802bc998>] out_of_memory+0x8b/0x203 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff8020f657>] __alloc_pages+0x245/0x2ce Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff8021336e>] __do_page_cache_readahead+0xd0/0x21c Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff80262824>] __wait_on_bit_lock+0x5b/0x66 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff88081d4d>] :dm_mod:dm_any_congested+0x38/0x3f Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff80213c47>] filemap_nopage+0x148/0x322 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff80208db9>] __handle_mm_fault+0x440/0x11f6 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff802639f9>] _spin_lock_irqsave+0x9/0x14 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff802666ef>] do_page_fault+0xf7b/0x12e0 Apr 2 17:18:28 s_local at webmail kernel:[<ffffffff8025f82b>] error_exit+0x0/0x6e Apr 2 17:18:28 s_local at webmail kernel: Apr 2 17:18:28 s_local at webmail kernel:Mem-info: Apr 2 17:18:28 s_local at webmail kernel:DMA per-cpu: Apr 2 17:18:28 s_local at webmail kernel:cpu 0 hot: high 186, batch 31 used:84 Apr 2 17:18:28 s_local at webmail kernel:cpu 0 cold: high 62, batch 15 used:57 Apr 2 17:18:28 s_local at webmail kernel:DMA32 per-cpu: empty Apr 2 17:18:28 s_local at webmail kernel:Normal per-cpu: empty Apr 2 17:18:28 s_local at webmail kernel:HighMem per-cpu: empty Apr 2 17:18:28 s_local at webmail kernel:Free pages: 2912kB (0kB HighMem) Apr 2 17:18:28 s_local at webmail kernel:Active:73144 inactive:40971 dirty:0 writeback:0 unstable:0 free:728 slab:4076 mapped-file:2 mapped-anon:114411 pagetables:2857 Apr 2 17:18:28 s_local at webmail kernel:DMA free:2912kB min:2916kB low:3644kB high:4372kB active:292576kB inactive:163884kB present:532480kB pages_scanned:1521701 all_unreclaimable? yes Apr 2 17:18:28 s_local at webmail kernel:lowmem_reserve[]: 0 0 0 0 Apr 2 17:18:28 s_local at webmail kernel:DMA32 free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 2 17:18:28 s_local at webmail kernel:lowmem_reserve[]: 0 0 0 0 Apr 2 17:18:28 s_local at webmail kernel:Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 2 17:18:28 s_local at webmail kernel:lowmem_reserve[]: 0 0 0 0 Apr 2 17:18:28 s_local at webmail kernel:HighMem free:0kB min:128kB low:128kB high:128kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no Apr 2 17:18:28 s_local at webmail kernel:lowmem_reserve[]: 0 0 0 0 Apr 2 17:18:28 s_local at webmail kernel:DMA: 12*4kB 8*8kB 3*16kB 0*32kB 1*64kB 1*128kB 0*256kB 1*512kB 0*1024kB 1*2048kB 0*4096kB = 2912kB Apr 2 17:18:28 s_local at webmail kernel:DMA32: empty Apr 2 17:18:28 s_local at webmail kernel:Normal: empty Apr 2 17:18:28 s_local at webmail kernel:HighMem: empty Apr 2 17:18:28 s_local at webmail kernel:89 pagecache pages Apr 2 17:18:28 s_local at webmail kernel:Swap cache: add 176874, delete 176874, find 114990/119550, race 0+0 Apr 2 17:18:28 s_local at webmail kernel:Free swap = 0kB Apr 2 17:18:28 s_local at webmail kernel:Total swap = 557048kB Apr 2 17:18:28 s_local at webmail kernel:Free swap: 0kB Apr 2 17:18:28 s_local at webmail kernel:133120 pages of RAM Apr 2 17:18:28 s_local at webmail kernel:5993 reserved pages Apr 2 17:18:28 s_local at webmail kernel:4267 pages shared Apr 2 17:18:28 s_local at webmail kernel:0 pages swap cached Apr 2 17:18:28 s_local at webmail kernel:Out of memory: Killed process 1592 (httpd).

[CentOS] Memory Leak with stock Squirrelmail, PHP, mysql, apache since 5.3

Thx, kfxHi, We are experiencing the same issue, however using Apache and Tomcat via Proxy AJP to server a Shibboleth IdP on CentOS 5.3 - stock RPMs. httpd-2.2.3-22.el5.centos tomcat5-5.5.23-0jpp.7.el5_2.1 Since upgrading to 5.3 we have noticed that overnight all 4GB of physical RAM and all 4GB of swap is eaten and the web service unresponsive. We can still SSH into the machine and restart Apache. This rectifies the issue. These are production boxes and subject to numerous connections, we are trying to isolate the trigger. However, the exact same configuration and applications being served under 5.2 exhibit no issue. I suspect it may be related to this bug, logged with the upstream: https://bugzilla.redhat.com/show_bug.cgi?id=497077 Cheers, J.
