https
I have an application running behind apache and apache only accepts https requests, my problem is that when a request is received I have to make a https request to another server in order to obtain the response and then return such response to the browser, the moment that I execute a https.request call I get a SIGSEGV. I won't be able to provide a piece of code that anyone can run and reproduce because this problem happens only when I run the entire application but I executed node with valgrind and it seems that the problem is coming from libcrypto.so, I think that maybe this is a concurrency issue in libcrypto.so but I'm not sure, the valgrind output is:

As I said before I could not create a simple script that could reproduce the issue but I'm making a https request like:
var payload = JSON.stringify({"key":"value"});
var options = {
hostname: '192.168.15.14',
port: 443,
path: '/path',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': Buffer.byteLength(payload)
}
};
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
var req_remote_outlets = https.request(options, function(res) {
res.on("error", (error) => {
console.log(error);
});
res.on("data", (chunk) => {
console.log(chunk.toString("utf8"));
});
res.on("end", () => {
});
});
req_remote_outlets.on("error", (err) => {
console.log(err);
});
req_remote_outlets.write(payload);
req_remote_outlets.end();I didn't find any source in the web that could help me with such issue, please tell me if I'm doing something wrong.
