We have about 10 Window''s services that we wrote in c#. We usethem to process row''s that we have queued up in various SQL tables. The services seem to hang at least once in any given 24 hour period. Once wereset the service, it goes about its processing business until the next timeit hangs. We are wondering if the hanging problem is due to a load issue(too many windows services on a single machine), a code flaw, or an inherentc# bug? We used to write NT services in VB6 using the ntsvc.ocx. Thoseservices never hung. I''m wondering if we are going to have to rewrite all ofour c# services in old school vb6.

No need to check this with a simple "hello world" service :-),I have acouple of services ,running for weeks now, performing some tasks at regularintervals using System.Threading.Timer. Is it possible that this custom class takes longer than the interval? And,when it''s the possibility exists, are you sure that, your custom class isthreadsafe, and there is no possibility for race conditions leading todeadlocks?I suggest you watch some resources like # of handles, # of run-able threadswhen the service runs and when it hangs.Another thing you can do is attach a debugger to your hung service and tryto find out where it hangs.
