 нет. (c)
 
 http://www.squid-cache.org/Doc/FAQ/FAQ-11.html#ss11.25
 
 11.25 FATAL: file_map_allocate: Exceeded filemap limit
 
    See the next question.
 
 11.26 FATAL: You've run out of swap file numbers.
 
    Note: The information here applies to version 2.2 and earlier.
 
    Squid keeps an in-memory bitmap of disk files that are available for
    use, or are being used. The size of this bitmap is determined at run
    name, based on two things: the size of your cache, and the average
    (mean) cache object size.
 
    The size of your cache is specified in squid.conf, on the cache_dir
    lines. The mean object size can also be specified in squid.conf, with
    the 'store_avg_object_size' directive. By default, Squid uses 13
    Kbytes as the average size.
 
    When allocating the bitmaps, Squid allocates this many bits:
         2 * cache_size / store_avg_object_size
 
    So, if you exactly specify the correct average object size, Squid
    should have 50% filemap bits free when the cache is full. You can see
    how many filemap bits are being used by looking at the 'storedir'
    cache manager page. It looks like this:
 
         Store Directory #0: /usr/local/squid/cache
         First level subdirectories: 4
 
         Second level subdirectories: 4
         Maximum Size: 1024000 KB
         Current Size: 924837 KB
         Percent Used: 90.32%
         Filemap bits in use: 77308 of 157538 (49%)
         Flags:
 
    Now, if you see the ``You've run out of swap file numbers'' message,
    then it means one of two things:
     1. You've found a Squid bug.
     2. Your cache's average file size is much smaller than the
        'store_avg_object_size' value.
 
    To check the average file size of object currently in your cache, look
    at the cache manager 'info' page, and you will find a line like:
         Mean Object Size:       11.96 KB
 
    To make the warning message go away, set 'store_avg_object_size' to
    that value (or lower) and then restart Squid.
 
 11.27 I am using up over 95% of the filemap bits?!!
 
    Note: The information here is current for version 2.3
 
    Calm down, this is now normal. Squid now dynamically allocates filemap
    bits based on the number of objects in your cache. You won't run out
    of them, we promise.
