c# - Service Fabric ASP.NET core website stops working after running for multiple days -


i have azure service fabric cluster. statefull service , stateless service. stateless service public facing asp.net core website. multiple sql connection strings , connection azure storage account.

when runs longer time (multiple days), hangs , i'm unable identify problem.

when restart (from sf cluster dashboard) node running service. starts working again.

in logs of asp.net core application last log. don't know

system.argumentexception: offset , length out of bounds array or count greater number of elements index end of source collection. @ system.arraysegment`1..ctor(t[] array, int32 offset, int32 count) @ microsoft.net.http.server.rawurlhelper.getpath(byte[] raw) @ microsoft.net.http.server.requesturibuilder.decodeandunescapepath(byte[] rawurlbytes) @ microsoft.net.http.server.request..ctor(requestcontext requestcontext, nativerequestcontext nativerequestcontext) @ microsoft.net.http.server.requestcontext..ctor(weblistener server, nativerequestcontext memoryblob) @ microsoft.net.http.server.asyncacceptcontext.iocompleted(asyncacceptcontext asyncresult, uint32 errorcode, uint32 numbytes) --- end of stack trace previous location exception thrown --- @ system.runtime.compilerservices.taskawaiter.throwfornonsuccess(task task) @ system.runtime.compilerservices.taskawaiter.handlenonsuccessanddebuggernotification(task task) @ microsoft.aspnetcore.server.weblistener.messagepump.d__22.movenext()

in event viewer (application, servicefabric admin, service fabric operational) of node running service nothing out of ordinary. happend multiple times.

is there place can find more internal logging? or error comes from?

my code run asp.net core looks this:

 protected override ienumerable createserviceinstancelisteners() {     return new serviceinstancelistener[]     {         new serviceinstancelistener(servicecontext =>             new weblistenercommunicationlistener(servicecontext, "serviceendpoint", (url, listener) =>             {                 serviceeventsource.current.servicemessage(servicecontext, $"starting weblistener on {url}");                  return new webhostbuilder().useweblistener()                             .configureservices(                                 services => services                                     .addsingleton(servicecontext))                             .usecontentroot(directory.getcurrentdirectory())                             .usestartup()                             .useapplicationinsights()                             .useservicefabricintegration(listener, servicefabricintegrationoptions.none)                             .useurls(url)                             .build();             }))     };

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
