openafs-server does not recover from crash

Hi,

our openafs-server has stopped working after a crash.

"bos status" shows all services online for all fileservers and DBservers.

udebug port 7003 works correctly from all fileservers and DBservers.

However, "strace -p $(pidof salvageserver)" shows an error:
connect(6, {sa_family=AF_UNIX, 
sun_path="/var/lib/openafs/local/fssync.sock"}, 110) = -1 ECONNREFUSED 
(Connection refused)
