SDKWhat should I do if the SDK crashes when shutting down an application? What should I do if, when using a system call, a program does not work properly in a child process? What do I do if I get the “Active sessions limit exceeded” error even though the current number of active sessions is within limits? Is it possible to make queries to different databases from the same application? What should I do if a VM has failed and it’s impossible to make a query?
