[squid-users] high volume of 'missing files' in cache....TCP_SWAPFAIL

[Linda W]

looking in the access log:

>  wc -l access.log
123246 access.log
>  grep TCP_SWAPFAIL access.log|wc -l
2369

 From the cache.log:
Ishtar:/var/log/squid# wc cache.log
 10263  92323 905184 cache.log
# grep "No such" /var/log/squid/cache.log|wc
   2642   27035  238727

Seems unlikely that a shutdown would cut it off:

so like for the files mentioned above:
Notice 24 and 25 are really gone --   and they likely should have expired...

Is there a command to run against the DB to have it check for
consistency?  I.e. maybe it will go away if the db is made consistent --
or... it will start doing this again after some period of time.
