Hi, I have an application which normally responds to user requests in the 100 -200 ms range with nominal API/CPU utilization, but occasionally will have a request simply time out. (infrequently and randomly).
Even more interesting, I have noticed in testing simulating 9-10 simultaneous users making simultaneous requests that groups of those users will get failures at the same time! It's been difficult to interpret the problems as it seems the requests are sometimes timing out in my servlet, and other times not being processed by front side. The requests that fail are writing a simple object or deleting a simple object from the DS. The objects are each in their on Entity Groups, so I can't see how the rate of writing or deleting (1/req) could be an issue. As I said, the errors are intermittent and infrequent, but when they do happen, it really screws up my sync protocol. Is there a possibility this is happening when my app is being launched on a new server or process? What can I do to debug this problem? I should say from a data model perspective, each of these users operates in a unique namespace. Thanks in advance. -Tom -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group. To post to this group, send email to [email protected].
