ESP32 reboots on ping (every then and now)

[bongoo1]

my application regularly checks the availability of other nodes in the subnet doing a ping.
while working fine most of the time, this unfortunately may result in a reboot, as soon as i execute the line
result = Ping.ping(checkip,1);
with chickip being the ip address.
there are times when everything works fine for a few days, and there are times when i get a reboot every few minutes.

i once managed to catch the output to the serial term on a reboot (see below).
but unfortunately, this does not really mean a lot to me ;-(
any idea what goes wrong here?

thanx for your help!

I have same situation. I use Ethernet module w5500. It works fine. But if I try to call Ping.ping(ip, 1) it throws an error:

assertion "Invalid mbox" failed: file "/home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/lwip/lwip/src/api/tcpip.c", line 374, function: tcpip_send_msg_wait_sem
