Hi everyone,
I got the urge to set up a server on my Raspberry Pi 4b (arm32v7) and have managed to compile and deploy everything (MariaDB, login, char and map server) successfully. However, after playing any character for a while I cannot log into it anymore, crashing the map server with a `Bus error` every time. New characters can still connect to the map server fine.
A few examples:
I played a Novice to about ~20 and logged out during the Thief job quest > the map server crashes whenever I try to play that character
I played another Novice to 17 and logged out in the Prontera church > I can still log in fine
I started a Novice, idled in the training center while browsing the code and logged out after a while > map server crashes for that character too
Running gdb on the core dump I got the following backtrace of the map-server binary:
#0 0x004aa018 in intif_parse_Registers (fd=7) at intif.cpp:1467
#1 0x004adcba in intif_parse (fd=fd@entry=7) at intif.cpp:3788
#2 0x0045d97c in chrif_parse (fd=<optimized out>) at chrif.cpp:1781
#3 chrif_parse (fd=7) at chrif.cpp:1753
#4 0x00653f1e in do_sockets (next=<optimized out>) at socket.cpp:1024
#5 0x00415906 in main (argc=1, argv=0xbefff784) at core.cpp:382
I didn't manage to understand what the cause is (other than it trying to read memory outside the range of fd). Can anyone tell me what the cause is and how I can fix it? Since I couldn't find any related issues on GitHub I expect it to be a setup problem on my end. It's highly confusing since I can play fine as long as I don't log out after passing some arbitrary playtime on each individual character..
I can provide more information if necessary, just point me in the direction of what you need!
Cheers, Valtaroth
EDIT: To add some more details:
I configured the servers with:
./configure --enable-packetver=20200401 --enable-prere=yes --disable-64bit
I have made no modifications to the source code besides disabling PACKET_OBFUSCATION in src/config/packets.hpp (which I later reverted in hopes of it being the cause).
I also have not added any custom data like items, npcs, maps or the like.
I also tried compiling the servers with cmake as outlined in the wiki and in this related post but the map server still behaved the same.
