vhserver segfaults #4058

When trying to start the server (either with vhserver debug, or directly from the commandline), I get two potential issues. First is the problem loading libparty.so... and the second is the segfault that ends with funlockfile.

I just upgraded to the latest steam build (10065092), so of course I suspect that.

I had this exact same issue.

If I delete libparty.so and adjust the command line in start_server.sh to not include "-crossplay", the server will start correctly.

There is obviously an issue here, and it just re-appeared after the update my server performed last night, which reverted my two changes (so I had to re-apply them).

Were you able to connect to your server? With the latest update today, if I remove libparty.so and set "-crossplay 0" on the commandline, the server starts... but my client says "Failed to connect".

TanerH Dec 22, 2022

I removed "-crossplay" entirely from the command line, but yes, clients are able to connect no problem!

Every time I upgrade the server, I have to make sure that libparty.so is deleted and '-crossplay' is removed from the command line. Otherwise the server either doesn't start at all, or starts but nobody can join.

Yeah, I ended up writing a wrapper for the "vhserver monitor" cron job, since that runs every 10m. That wrapper just runs a "fix segfault" script I wrote both before and after the "vhserver monitor" command (probably overkill).

My "/home/vhserver/fix_segfault.sh" script:

#!/bin/bash

LIBPARTY="/home/vhserver/serverfiles/valheim_server_Data/Plugins/libparty.so"
STARTSERVER="/home/vhserver/serverfiles/start_server.sh"

if [ -e $LIBPARTY ]; then
        #echo "Deleting $LIBPARTY"
        rm $LIBPARTY
fi

if [ -e $STARTSERVER ]; then
        perl -i.bkp -pe 's/-crossplay//' $STARTSERVER
fi
