I just recently installed yacy, it's I hope installed as a "Senior" node however I have it proxied through
Apache for https access by my customers, so it is raw at http://www.eskimo.com:8090/ and proxied
For some reason after operating a number of hours it just locks up. The process is still running but it stops responding. The scropt stopYACY.sh locks also at this point so I end up doing a killall -u yacy; killall -9 -u yacy (I have it running under UID yacy) and then restart it and it works again, for a while.
