Killing all of your system's sleeping processes isn't going to solve any problem let alone the problem you're having. Being structured and methodical in your approach is much better than flapping around wildly. Personally I find Scientific Method (others call it something different) a wonderful tool to pull out of the system administration kitbag when ...

First off, you have run out of memory. Your VPS has 2GB of RAM and 4GB of swap. The 2GB of RAM is all used up, and the swap is maybe 3/4 full. At this point, on any system I manage, there is an alarm that repeats every five minutes until someone acknowledges the problem, it is that serious. So you need to figure out what's using all the memory. ...

You need to have yum version 3.2.26 or above and if you don't have it install yum-utils package which comes with the yumdb script. Using yumdb you can set a certain package to be kept from being removed on updates. yum update yum yum install yum-utils yumdb set installonly keep kernel-2.6.32-279.2.1.el6.x86_64

You have about 1692m in free memory according to Linux. In the top "Mem" line it would seem like your memory is almost 99% (7793m / 7840m) but in reality you're only using about 78% of available memory. See also http://www.linuxatemyram.com/ for a more in-depth explanation. Free vs Top vs /proc/meminfo Process memory. Adding up the memory used by ...

If you had created the PV as partition, you would have to shrink the PV first with pvresize --setphysicalvolumesize 5124M /dev/sdb and then resize the partition in the partition table with tools like fdisk or parted. But in your case you cannot create new partitions there since the PV encompasses the whole drive, so you can't safely make a fresh partition ...

Your question says you are "struggling to work out why this waited for so long before being re-tried", but it seems to me that those logs are definitive: your mail server isn't waiting 12 days before re-trying sending. It's retrying it quite often (though without all the logs I can't say how often), but the remote server is being consistently unavailable. ...

Theres a lot of free memory, but these zones are totally fragmented: Node 0 Normal: 1648026*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 6592104kB Node 1 Normal: 8390977*4kB 1181188*8kB 0*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB There are very few non-zero order pages left, none in one ...

There are two solutions to this issue: 1) You can regenerate the default self-signed certificate using OpenSSL: openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/pki/tls/private/localhost.key -out /etc/ssl/certs/localhost.crt<br/><br/> 2) You can search the Apache config files and replace the self-signed cert with the new ...

your ssl certificate issuer should provide you free replacement or reissue. Just go to digicert and ask them. Generate new key files from server and reissue ssl. Make sure the new ssl should be SHA2 only.

In general case innodb_force_recovery mode is supposed to let a user to start InnoDB and dump valuable data. A common belief InnoDB will heal tablespace after enabling innodb_force_recovery. No, it won't. (In some cases you can fix a tablespace dropping particular tables, but that's another story). If you are lucky enough and MySQL starts the next step is ...

A part of the reason you might want to implement a RAID array is the read speed improvement. Using only a single disk to read from, but writing to both, smells wrong. If your actual problem is that you are experiencing worse read times since replacing a disk in your RAID setup, you might want to troubleshoot that disk instead of working around it. Here ...

There is an easier way to add routes... This file - /etc/init.d/network - is launched when the PC is booting, and it uses a file /etc/sysconfig/static-routes to add static routes You have to create it because it doesn't exist. If you read carefully the file /etc/init.d/network, it reads in this file each line to add routes, those line must begin by "any", ...

Although not a fix for your underlying problem, the mdadm command has the --write-mostly option: -W, --write-mostly subsequent devices listed in a --build, --create, or --add command will be flagged as 'write-mostly'. This is valid for RAID1 only and means that the 'md' driver will avoid reading from these devices if at all possible. This can be useful ...

I suspect that you are trying to start the sshd application with a non-root user. The permissions of the host key file only allow root to read them. 4 -rw-r--r--. 1 root root 2047 Nov 6 09:07 ssh_config 4 -rw-------. 1 root root 3879 Nov 6 09:07 sshd_config 4 -rw-------. 1 root root 672 Jun 23 13:32 ssh_host_dsa_key 4 -rw-------. 1 root ...

Include .i686 along with the package name to install the 32bit package. To install the 64bit package you would use .x86_64. yum install gcc.i686

I had a similar issue recently with one of the domains we relay for. There was a single message in the queue for that domain which caused their gateway to hang and not accept the message. This arrived while their gateway was unavailable for maintenance (so we built up a queue of messages for them before they were back in service). On subsequent queue runs ...

This issue has been fixed for me. "Shell Fork Bomb Protection" was blocking SVN binary execution with non-root users. CPANEL -> Securty center -> Shell Fork Bomb Protection -> Disable Protection "Unknown Hosts" and "Out of memory - terminating application" both svn issues solved after disabling protection.

You may be past this issue, but I wanted to update with the method that worked easily for me. Here was my situation: I was building several python27 SCL RPMs from downloaded egg files using a script to do everything - side note: This was how I pulled in all of the dependencies for our Python Django web app and is run from within the Atlassian Bamboo plan ...
