I wish I knew what causes this - I would stop it - but it happens so
rarely that I cannot diagnose the cause. 

However, it is easy enough to fix:-

stop the node.

login is as the sysop user.
 
$ cd /spider/data
$ rm users.v*
$ perl user_asc

check that users.v3 is of reasonable size, otherwise do the 'perl
user_asc' step again, then restart the node.
