Mongrel stops responding after period of inactivity
Hi I''m running a 2-instance Mongrel cluster behind Apache 2.2.4 with Rails 1.2.3. If no requests are received by the application for several hours (this usually happens overnight) then Mongrel stops responding and no requests are detected by Rails (at least nothing is in the Rails log). Nothing untoward is in the Mongrel log. If you try and visit the application, the request times out

Hi I posted this to the Ruby on Rails Talk group but I thought I''d post it here too as it''s probably a more appropriate group. Hope this is ok.

Segmentation fault
Hi Federico, Segfaults are 100% not by design.  Typically if something seg faulted, either there is a logic bug or a component mismatch. The you should definitely be able to use more than one connection (we use multiple connections with postgres odbc with no issue). If Asterisk segfaults when using odbc Try this: - use ps and get the pid of Asterisk - run gdb, attach to the asterisk pid - do

mysql replication - problems
Hey everybody, I'm trying to get mysql master/slave replication to work under SSL. I've created the certs for both the slave and the master. I've configured the master and slave my.cnf. And it does appear that replication is actually working. Master is actually MariaDB (version 5.5.41-MariaDB-log, and the slave is MySQL (version 5.5.41-log). But there are two issues I'd like to

You should be able to define multiple data sources. However I'm having my own issues. I have my dialplan accessing one maria database which is hosted locally on the asterisk server then logging cdr with odbc adaptive which connects to maria on a remote machine. This works fine except when the remote server is out of reach the calls zombie and eventually lead to a fault. The cli imply that the

I'm trying to redirect MariaDB logs to `/var/log/mysql/*.log` files as shown below on the `/etc/my.cnf.d/server.cnf` file: # # These groups are read by MariaDB server. # Use it for options that only the server (but not clients) should see # # See the examples of server

ActiveRecord does not close database connections?
I have an application that creates quite a few threads. I keep getting the "mysql too many connections" error. ActiveRecord does not close the connection once a thread had died out. To make things worse mysql has a wait_timeout variable that would basically kill off these connections for me, but there is a bug and I can not change the value of it. I have tried at least 10 different

High system load but low cpu usage
I'm trying to figure out what's causing an average system load of 3+ to 5+ on an Intel quad core. The server has with 2 KVM guests (assigned 1 core and 2 cores) that's lightly loaded (0.1~0.4) each. Both guest/host are running 64bit CentOS 5.6 Originally I suspected maybe it's i/o but on checking, there is very little i/o wait % as well. Plenty of free disk space available on all

strange sar statistics: total CPU 90% in userspace, but CPU 0 and 1 only 1%
Hi Centos Users The server (ProLiant DL380 G5, Centos 4.3) was not responsible anymore (SSH), fans rotated at full power and the console was blank. After restart it seems to be fine. Now I am analyzing sar statistics (in system logs nothing special, unusual). The hardware monitoring with HP tools didn't work. # sar -P ALL Linux 2.6.9-34.ELsmp (cent061) 01/15/2008 12:00:01 AM

SAR
Folks, At what point in iowait should I start to worry about having a bottleneck, or is this something that can't be answerd with a single integer? According to sar, after my last reboot to turn off hyperthreading as a test, at one time, I see 4.9% iowait, but then one minute later, it droped back to 0.01%, and rarely even gets to 1.0%, at least what I remember from yesterday. ?

Help in troubleshoot cause of high kernel activity
Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the
