Hai to all, i have got a problem related to Threads in java. In our application we are using some 40 threads (ie they are used to send the request and fetch the values of the parameters of a particular device )The problem is that some of the threads are going into unknown state (we can say threads are getting hanged) but all the threads has to be run continuously with timers.Our application is using solaris9.0.Is there chance of the OS causing the problem of thread hanging?kindly mail ur comments and site information to varun@indusnetworks.com and its very very urgentregardsvarun paramalaAt present we are using some monitor thread to monitor our threads but we are not successful in that.
