Hi, environment: new Centos 6 installation out of the box. somebody has an idea what causes this error mail to be sent? ---8<--- Subject: Cron <root@fileserver1> /usr/local/asc/bin/ascservicemonitor 2>&1 >/dev/null Content-Type: text/plain; charset=UTF-8 Auto-Submitted: auto-generated X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> X-Cron-Env: <USER=root> Message-Id: <20120228122702.1F468101951(a)XXXXXXXXXXX.XXXXX.de> Date: Tue, 28 Feb 2012 13:27:02 +0100 (CET) /bin/sh: /usr/local/asc/bin/ascservicemonitor: No such file or directory ---8<--- This pops up every three minutes.

Re: [CentOS] Centos 6.x and Freenx issue..Solved!!
by Tom Bishop 28 Feb '12

28 Feb '12

Thanks much to* Christoph *for pointing me in the right direction, appears to be an issue with the latest Vmware -tools, not sure I did a clean install with the opensource ones to see if they had the same issues but applying both of the fixes in the link post solves the problem with running the latest freenx and nx rpms found in the repo. Thanks again :) On Tue, Feb 28, 2012 at 5:36 AM, christoph.galuschka(a)chello.at < christoph.galuschka(a)chello.at> wrote: > Tom, > > take a look at this post, maybe it solves your problem. > > http://lists.centos.org/pipermail/centos-devel/2012-February/008570.html > > cheers > Christoph >

strange memory issues with CentOS 6.2 on VPS
by Tomas Vondra 28 Feb '12

28 Feb '12

Hi all, today we've encountered quite strange issues with memory allocation on one of our VPS running CentOS 6.2. So far I've been unable to determine what's causing it - hopefully someone here will know what's up. The VPS is a "small" machine - just 512MB of RAM, 1 CPU, running 6.2. with current kernel (2.6.32-220.4.2.el6.x86_64, but I've tried the 2.6.32-71.el6.x86_64 too). There's a quite common stack installed, i.e. Nainstalován je na něm celkem standardní stack - apache, php, postgresql, postfix, dovecot, memcached and ssh. Basically nothing exotic, everything from official repos (except from postfix and postgresql). The machine is not heavily used. More detailed logs (than posted here) are available here: http://pastebin.com/vYxRUyUX We've been hitting some I/O utilization issues (cause by other VPS instances on the same hw) so we've migrated to a different physical hw. After the migration, the VPS started failing because of memory alloc issues - the services fail either at startup time or when processing the requests - although there's enough free mem: [root@vps audit]# free total used free shared buffers cached Mem: 502728 294224 208504 0 18604 163608 -/+ buffers/cache: 112012 390716 Swap: 0 0 0 i.e. about 200 MB of free memory, but apache fails because of segfaults when forking a child process: [16:49:51 2012] [error] (12)Cannot allocate memory: fork: Unable to fork new process [16:51:17 2012] [notice] child pid 2577 exit signal Segmentation fault (11) or when processing requests: [26 16:30:16 2012] [error] [client 66.249.72.1] PHP Fatal error: Out of memory (allocated 262144) (tried to allocate 523800 bytes) in Unknown on line 0 The memory_limit in PHP is set to 32MB, so it's not the case. Similar issues happen to PostgreSQL: 16:42:01 CET pid=2504 db=xxxxxx-drupal user=xxxxxx FATAL: out of memory 16:42:01 CET pid=2504 db=xxxxxx-drupal user=xxxxxx DETAIL: Failed on request of size 2488. 16:42:01 CET pid=2438 db= user= LOG: could not fork new process for connection: Nelze alokovat paměť 16:42:01 CET pid=2438 db= user= 4f4a5247.986:21 LOG: could not fork new process for connection: cannot allocate memory I have absolutely no clue what's causing this / how to fix it. According to free/vmstat there's about 200MB of free RAM all the time, so I have no idea why the alloc calls fail. What makes is even more puzzling is that after adding a swapfile, all the issues suddenly disappear, although the swapfile is not used at all ... and it's not possible to disable it because of memory alloc. # dd if=/dev/zero of=swap.img bs=1024 count=409600 # mkswap swap.img # swapon swap.img ... now the services are starting fine ... # swapon -s Filename Type Size Used Priority /root/swap.img file 399992 0 -1 # free total used free shared buffers cached Mem: 503412 294192 209220 0 11740 99980 -/+ buffers/cache: 182472 320940 Swap: 399992 0 399992 # swapoff swap.img swapoff: swap.img: swapoff selhal: Nelze alokovat paměť Any ideas what might cause this? The fact that I haven't noticed these issues before the migration are probably caused by a swap file - I've manually added it during a maintenance and forgot to remove it after that, but it disappeared when the machine was rebooted during migration. There's a SELinux enable, but I doubt it's causing the issues - there's nothing in audit logs except for an information that there was a segfault. Nothing suspicious. Otherwise it's just a standard CentOS install, the only thing I had to tune a bit were kernel limits (in sysctl.conf) related to shared memory (because of the database). Currently there's kernel.shmmax = 68719476736 kernel.shmall = 134217728 vm.swappiness = 0 vm.overcommit_memory = 2 which should be fine IMHO ... any ideas? regards Tomáš

Centos 6.x and Freenx issue..
by Tom Bishop 28 Feb '12

28 Feb '12

Finally got a chance to install Centos 6.x x86_64 version and having an issue with the latest version of freenx. This is a desktop install on a esxi 5 with all updates and only thing I have installed is the latest vmware tools. When I enable the extras repo and install the nx-3.5.0-1.el6.ay.x86_64.rpm and freenx-0.7.3-8.el6.ay.x86_64.rpm. When I try to logon the desktop pops up but I get the little busy circle and it never completes, I am unable to close the session or do anything to the freenx window. Here is the odd, part, if I install the earlier versions from toracat, freenx-0.7.3-7.el6.ay.x86_64.rpm and nx-3.4.0-7.el6.ay.x86_64.rpm the session comes up and works fine,I can exclude the updates but wondering if anyone has any idea of what I might try to get it to work with the latest, thanks in advance.
