Recently my Fedora running under level 3 begun freezing. It was running for about four months without any failures, but now it freezes almost every day, even twice a day. Sometimes it comes back itself, sometimes hard reboot is needed.
This is a remote server where I connect through ssh. When freezed, can't connect to ssh, can't open http and asterisk which is running on this system is not accepting calls.
I couldn't find anything interesting in log files, only this when this system is loading:

Hi everyone,
I hope this question goes here. Anyways, I have a unique situation where my friend's comp has Fedora installed and wants to add Win XP as a dual boot without formatting the drive. Is it possible to create a partition on the current hard drive and then install win xp? I couldn't find... (4 Replies)
this is purely for posterity but it took me a while to find this solution online. 10.1 comes wanting to install the stable releases of xorg and the kernel. However on many platforms (especially with intel video) the result is an xorg that functions for a few minutes but then hangs up and prevents... (0 Replies)

I will probably also want to... (0 Replies)

My script that I wrote is no longer running, but just freezing when I execute it.
Before it was running and showing me where errors were, now when I execute it, nothing happens and i cant type anything into the command screen.
The script was a looping script, what could be going on? (8 Replies)

SSS_DEBUGLEVEL(8) SSSD Manual pages SSS_DEBUGLEVEL(8)NAME
sss_debuglevel - change debug level while SSSD is running
SYNOPSIS
sss_debuglevel [options] NEW_DEBUG_LEVEL
DESCRIPTION
sss_debuglevel changes debug level of SSSD monitor and providers to NEW_DEBUG_LEVEL while SSSD is running.
OPTIONS -c,--config
Specify a non-default config file. The default is /etc/sssd/sssd.conf. For reference on the config file syntax and options, consult the
sssd.conf(5) manual page.
NEW_DEBUG_LEVEL
Bit mask that indicates which debug levels will be visible. 0x0010 is the default value as well as the lowest allowed value, 0xFFF0 is
the most verbose mode. This setting overrides the settings from config file.
Currently supported debug levels:
0x0010: Fatal failures. Anything that would prevent SSSD from starting up or causes it to cease running.
0x0020: Critical failures. An error that doesn't kill the SSSD, but one that indicates that at least one major feature is not going to
work properly.
0x0040: Serious failures. An error announcing that a particular request or operation has failed.
0x0080: Minor failures. These are the errors that would percolate down to cause the operation failure of 2.
0x0100: Configuration settings.
0x0200: Function data.
0x0400: Trace messages for operation functions.
0x1000: Trace messages for internal control functions.
0x2000: Contents of function-internal variables that may be interesting.
0x4000: Extremely low-level tracing information.
To log required debug levels, simply add their numbers together as shown in following examples:
Example: To log fatal failures, critical failures, serious failures and function data use 0x0270.
Example: To log fatal failures, configuration settings, function data, trace messages for internal control functions use 0x1310.
Note: This is new format of debug levels introduced in 1.7.0. Older format (numbers from 0-10) is compatible but deprecated.
