Detect Socket timeout in tcpdump capture

Hello,

I detect these errors in my logs :
Socket timeout calling url [http://server:port/bla/soap/selfcare/infoRapide]
Unable to make proxyRequest

I've made a tcpdump capture this way :

Code:
tcpdump -i eth0 -s 0 -w /app/captura.pcap port 8080

But I'm fairly new in reading .pcap files with wireshark... too much info for me. So I would like to know if you have some hints in what exactly should I look for in the capture to detect the errors I see in my logs "Socket timeout / Unable to make proxyRequest ".

Thanks

Log::Handler::Output::Socket(3pm)			User Contributed Perl Documentation			 Log::Handler::Output::Socket(3pm)

NAME
Log::Handler::Output::Socket - Send messages to a socket. SYNOPSIS
use Log::Handler::Output::Socket; my $sock = Log::Handler::Output::Socket->new( peeraddr => "127.0.0.1", peerport => 44444, proto => "tcp", timeout => 10 ); $sock->log(message => $message); DESCRIPTION
With this module it's possible to send messages over the network. METHODS
new() Call "new()" to create a new Log::Handler::Output::Socket object. The following options are possible: peeraddr The address of the server. peerport The port to connect to. proto The protocol you wish to use. Default is TCP. timeout The timeout to send message. The default is 5 seconds. persistent and reconnect With this option you can enable or disable a persistent connection and re-connect if the connection was lost. Both options are set to 1 on default. dump Do you like to dump the message? If you enable this option then all messages will be dumped with "Data::Dumper". dumper Do you want to use another dumper as "Data::Dumper"? You can do the following as example: use Convert::Bencode_XS; dumper => sub { Convert::Bencode_XS::bencode($_[0]) } # or maybe use JSON::PC; dumper => sub { JSON::PC::convert($_[0]) } connect This option is only useful if you want to pass your own arguments to "IO::Socket::INET" and don't want use "peeraddr" and "peerhost". Example: connect => { PerrAddr => "127.0.0.1", PeerPort => 44444, LocalPort => 44445 } This options are passed to "IO::Socket::INET". log() Call "log()" if you want to send a message over the socket. Example: $sock->log("message"); connect() Connect to the socket. disconnect() Disconnect from socket. validate() Validate a configuration. reload() Reload with a new configuration. errstr() This function returns the last error message.
