I have a batch job in an APP server in a SharePoint Production farm that executes Fast Search queries. Basically, the batch job calls the Search web service to execute search queries.
Previously, when I run this batch job in the APP server, it's able to complete without errors.
Now, when I run the batch job in the APP server, it's throwing me the error:
The search request was unable to execute on FAST Search Server.. Stack Trace: at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object parameters)
However, when I run the batch job in the WFE server, it's able to complete without errors.
More details are: * Search Topology: 3 crawl components; 1 is at the FAST search server and the other 2 are at 2 WFE servers. 1 admin component at the FAST Search server. 1 query component at the FAST Search server. * Version: SharePoint 2010
Would greatly appreciate any ideas and suggestions on how to troubleshoot this issue!
