"Preflight journal health check" issue caused by a grep command not coping well with non ascii characters.
The issue can be fixed in //guest/perforce_software/sdp/dev/Server/Unix/p4/common/bin/p4d_base by replacing line 177:
tail -10000 "$P4JOURNAL" 2>/dev/null | grep -v "@vv@" > "$TmpJnl" 2>> "$TmpLog"
by
tail -10000 "$P4JOURNAL" 2>/dev/null | grep -av "@vv@" > "$TmpJnl" 2>> "$TmpLog"
