The process likely unexpectedly failed.
Would you be able to replicate it for us? In a minimal sample repo?
Is this failing deterministically for the same template/data? If yes, could you provide it?

Currently I am using just one template, and that is throwing this error.
This error is occurring on one of my staging server (Adding the logs/details below).
The application is deployed on Kubernetes.

My Startup.cs code:

services.AddJsReport(new LocalReporting()
.UseBinary(RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ?
jsreport.Binary.JsReportBinary.GetBinary() :
jsreport.Binary.Linux.JsReportBinary.GetBinary())
.KillRunningJsReportProcesses()
.RunInDirectory(_reportPath)
.TempDirectory(_tempPath)
.Configure(cfg =>
{
cfg.Chrome = new ChromeConfiguration()
{
Timeout = 2400000
};
cfg.TemplatingEngines = new TemplatingEnginesConfiguration()
{
Timeout = 2400000
};
cfg.Extensions = new ExtensionsConfiguration()
{
Phantom = new PhantomConfiguration()
{
Timeout = 2400000
},
Express = new ExpressConfiguration
{
InputRequestLimit = "500mb"
},
Scripts = new ScriptsConfiguration()
{
Timeout = 2400000
}
};
cfg.Logger = new LoggerConfiguration() { Transport = new LoggerTransportConfiguration() { Transport = "console", Level = "debug" } };
cfg.AllowedLocalFilesAccess();
cfg.FileSystemStore();
cfg.EnableRequestReportTimeout = true;
return cfg;
})
.AsUtility()
.Create());

Method where I am generating report:
Environment.SetEnvironmentVariable("chrome_strategy", "chrome-pool");
Environment.SetEnvironmentVariable("chrome_numberOfWorkers", "2");
Environment.SetEnvironmentVariable("extensions_express_renderTimeout", "2400000");

var report = await _jsReportMVCService.RenderByNameAsync("returnTemplate", reportData);

Does the same fail for you on local?
Are you able to share the template you are rendering?

I tried on local dev machine (IIS express, IIS and docker) it is working fine. Also checked on a windows server IIS, it worked smoothly on it as well.

On Kubernetes (linux containers), I have 2 identical instances with similar config (but different network/domain).
It is working fine on one of it, while this error is generated on the other instance.
I checked the 3000 port and it is also not blocked.

Unfortunately, I am not able to share the template at the moment.

It could be killed with OOM. Check on that using dmesg or another way you are familiar with.

OOM is not the case here. I have already tried with double the size of memory which I was using for the other working instance. Then tried with max memory as well.

any suggestion?

Could you try to turn off the keepAlive?

AsUtility().KeepAlive(false)

New Error - Error rendering report: instance has been daemonized and initialized successfully rendering has finished with errors:A critical error occurred while trying to execute the render command . or user doesnt have permissions to read it:

Please try to clean the _tempPath you use and restart the app.
