Application showing "Connection Time Out" very often
Hi,
We have a web serveer running on Apache-Tomcat-6.0.32. For 2 months continuously, we noticed that the app on this server setup has been frequently sending out intermittent "Connection Time Out" issues.
On the OS side, I investigated a lot of things,
1) tcpdump : did not find anything suspicious (no large flooding of suspicious IP, etc)
2) In the apache access_log nothing suspicious either.
3) netstat -an, tulpn : No timeout/dead connection
4) telnet to port 80 is OK
Thus, my teammate concluded that it could be a bug in the tomcat version 6.0.32 itself. Is this possible/true? How can we confirm this?
We use "Uptime" as a monitoring tool, and it sends updates every 3 mins. Whereas other monitoring tools send alerts every 5 mins or more, and do not show the "Connection Time Out" problem.
Is "Uptime" an unstable monitoring tool?

audio::mpd::common::time
Audio::MPD::Common::Time(3pm) User Contributed Perl Documentation Audio::MPD::Common::Time(3pm)
NAME
Audio::MPD::Common::Time - class representing time of current song
VERSION
version 1.120881
DESCRIPTION
Audio::MPD::Common::Status returns some time information with the "time()" accessor. This information relates to the elapsed time of the
current song, as well as the remaining and total time. This information is encapsulated in an Audio::MPD::Common::Time object.
An Audio::MPD::Common::Time object does not update itself regularly, and thus should be used immediately.
Note: one should never ever instantiate an Audio::MPD::Common::Time object directly - use the mpd modules instead.
ATTRIBUTES
$time->time;
The time passed to the constructor, used to compute all others values (see methods). It is the time value (on the "time" line) of what the
MPD server returns to the status command. Defaults to "0:0".
METHODS
my $str = $time->sofar;
Return elapsed $time ("minutes:seconds" format).
my $str = $time->left;
Return remaining $time ("minutes:seconds" format).
my $str = $time->left;
Return total $time ("minutes:seconds" format).
my $percent = $time->percent;
Return elapsed $time (percentage, 1 digit).
my $secs = $time->seconds_sofar;
Return elapsed $time in seconds.
my $secs = $time->seconds_left;
Return remaining $time in seconds.
my $secs = $time->seconds_total;
Return total $time in seconds.
my $mins = $time->sofar_mins;
Return minutes part of elapsed $time.
my $secs = $time->sofar_secs;
Return seconds part of elapsed $time.
my $mins = $time->left_mins;
Return minutes part of remaining $time.
my $secs = $time->left_secs;
Return seconds part of remaining $time.
my $mins = $time->total_mins;
Return minutes part of total $time.
my $mins = $time->total_secs;
Return seconds part of total $time.
