RECURRENT CURL TO A VIRTUAL SERVER FAILING

There is an issue on my network. i created a Virtual Server for backend servers running some Oracle Enterprise Linux server based applications.

 

When the url string is accessed on a browser (http://10.184.1.226/services/EIAproxy?wsdl), the page loads, on several tabs if accessed concurrently. Using SOAP,the same page loads accurately,

 

On some VM's, when a curl command is made to the url, repeatedly, the connection fails intermittently.

 

A tcp dump on F5 shows TCP Spurious retransmission errors on Wireshark for the many putty connections from those VM's.

 

What could be the problem on Putty,for these connections to succeed and fail?

 

Is there any change that can be done on F5, to accept all TCP connections from clients,even when initial SYN requests haven't yet been acknowledged?

 

  • Hi Kazeem,

    Not sure if this will help you but maybe you can try to icrease the connection timeout of the client (curl) using the following option :

    curl --connect-timeout
