I belive this is the same problem because i applied the patched up versions mentioned in this issue #932
and it seems to me that it works so far. But additional test are required

[DShabroff]

It took some time for testing. Reboots have become less frequent. I downloaded 2 server pages on one computer, and 3 on another. The reboot now occurs once in 4-6 hours and does not depend on the number of open copies. I haven't tested it with one open copy, but I will test it and writeabout. Below decoded error code

Does your client reconnects on websocket if its lost?

[DShabroff]

Does your client reconnects on websocket if its lost?

Yes, sometimes I see the massage: Client reconnected with ID that it got is...

[DShabroff]

In the case of one open page, no processor resets are observed. As it was before.

[xlyric]

if it can help :
personnaly the esp32 hang with the mode "processor"
request->send(SPIFFS, "/index.html", String(), false, processor);
and work only with
request->send(SPIFFS, "/index.html", "text/html");
I processing data after

[DShabroff]

request->send(SPIFFS, "/index.html", "text/html");

It's not compilng yet. In my code Processor - is the simple function:

String processor(const String& var) { return "Waiting Data"; }
If I write this function without argument, I get compile error:

ADXL3xx:503:60: error: invalid conversion from 'const char*' to 'const uint8_t* {aka const unsigned char*}' [-fpermissive]
request->send_P(200, "text/html", index_html, processor);

Same compile eror I get with this code:

request->send_P(200, "text/html", index_html, "Waiting Data");

This variant:
String PageWait = "Waiting Data"; request->send_P(200, "text/html", index_html, PageWait);

get compile eror is:

ADXL3xx:504:59: error: no matching function for call to 'AsyncWebServerRequest::send_P(int, const char [10], const char [2648], String&)'
request->send_P(200, "text/html", index_html, PageWait);

I think last argument in function request->send_P(200, "text/html", index_html, PageWait);` must be the refer to function.

And there is:

void AsyncWebServerRequest::send_P(int code, const String& contentType, PGM_P content, AwsTemplateProcessor callback)

WebRequest.cpp(808)

[Pablo2048]

Yes, the last argument is pointer to the function. Try to use:

String processor(const String& var) { return String("Waiting Data"); }

[DShabroff]

String processor(const String& var) { return String("Waiting Data"); }

I think it's same as I use:

String processor(const String& var) { return "Waiting Data"; }

But I will try your variant. Thank you.

[Pablo2048]

I think it's same as I use:

String processor(const String& var) { return "Waiting Data"; }

It's not - Your function return const char *, while required return is String() object...

[DShabroff]

Reset are rare but still occur. Once per 20 hours of work. 4 pages open.

If no reset, the server is frozen for me. The esp still working doing its job but i cant reach the web. I experience this with the fixed libs.
