No response message from Web Cache

Hi,

We are facing a strange and serious problem with our Oracle infrastructure. We have running a web application that uploads files to the database server. But we have found out that if we try to upload a ZIP file (in the application, uploading a ZIP file means that it uncompresses the ZIP file and copy the zipped files one by one to the database server, therefore this operation can take a while), it comes an error message of the type:

No Response from Application Web Server

We didn't find any especial configuration for a timeout in the application server and http server. We also checked the timeout for the web cache that we also use, and seems to be alright (very much longer that the time to crash). When using the application without going through the Web Cache (calling directly the application server), it works well!!! On the other hand, we thought in a relation between the size of the files and the effort of the application to process them and the "No response", but we have successfully uploaded other documents bigger than the ZIP file. When checking the LOG files of the Web Cache and the Apache and application server, we find the following:

Could it be that the Web Cache sent a request to the application server and because of an unknown reason, it received a response that made it to show the "No response" message. Or could it be that the Web Cache is sending request and not receiving any response from the application server, or that there is some timeout configuration that we didn't find??? Please, help!!!!

Thanks in advance,
Luis
