ESP32-S3 Crash on transmitting TCP packet

[jared52005]

Every time when I will try to transmit from KLINE via TCP (IP RAW layer), then LWIP appears to crash on ECU response of 1A9B.
First I was experiencing this:

W (29068) Passive_Kline.c: ISO14230 crap bytes:  
I (29068) Passive_Kline.c: 0x3fc9eca0   00 00 00 00 00 00 00 00  00 00 00 00 00 55 ef 8f  |.............U..|

Then after I have increased memory of tcpwsraw_thread from 4096 to 8192 bytes, error has changed on

----

I am not sure what exactly is a cause. It might be related to length of a TCP packet. I will need to better pinpoint it and see if it is the issue on ISO15765 and VWTP2.0 and on older ESP32

pvPortMalloc(sizeof(length)) allocating only 4 bytes for a whole frame instead of allocating length amount of bytes
