NAV Web Service Issue in Concurrent User Handling

NAVPRAKASH

Dear NAV Expert’s,

I have created a XMLPORT and exposed it through the Code Unit as Web Service. The XMLPORT will loop for 10 times and returns 10 dates as XML. I simply incremented the data variable for 10 times. For example the Start Date = TODAY and End Date = TODAY + 10D. We have created Web Application using Java to consume the Web Service and show the result data set. This is providing the correct result in normal testing, but when we tested the result with the Concurrent user by using the Java Testing tool it’s returning wrong dates.

When it reaches 25 concurrent users in Testing tool, it’s started giving some responses with weird dates like start date = 01-11-1970, and this happens not in all responses. When the concurrent users reach around 30, for 50 requests, on an average 2 responses are failed and returns invalid date.

Is this because of NAV Service is unable to handle the Concurrent User? Have you ever face this issue using Web Service. Any Suggestions is highly appreciated.

Thanks in Advance

Which build? Have you contacted the Microsoft support regarding that?

Can you post code here? I newer seen something like this before. Middle tier handle concurrent users without any issue in my experience.
