Jeff,

This is just the overflow groups being added as needed.  You can run guide
to find a better modulo/block size, but a little data overflow is ok.

Thanks,

Subject: [U2] Unidata file size

I'm running Unidata 7.1.8 on Solaris 9.  I have a static hashed file with 
modulo 5009 and block size of 16K.  I didn't think static hashed files 
would change size at the OS level, but this one is.  Am I just wet 
behind the ears or do I just misunderstand static hashing?

Here's the file this afternoon:

-rwxrwx---   1 datatel  staff    102105088 Apr 13 12:32 WWW.STATE

and about two hours later:

-rwxrwx---   1 datatel  staff    121372672 Apr 13 14:44 WWW.STATE

Since I know someone might ask:

File name                             = WWW.STATE
Number of groups in file (modulo)     = 5009
Static hashing, hash type             = 0
Block size                            = 16384
File has 62 groups in level one overflow.
Number of records                     = 505
Total number of bytes                 = 4673742

Average number of records per group   = 0.1
Standard deviation from average       = 0.3
Average number of bytes per group     = 933.1
Standard deviation from average       = 9586.7

Average number of bytes in a record   = 9254.9
Average number of bytes in record ID  = 21.6
Standard deviation from average       = 28809.0
Minimum number of bytes in a record   = 51
Maximum number of bytes in a record   = 381892

Minimum number of fields in a record  = 1
Maximum number of fields in a record  = 827
Average number of fields per record   = 80.9
Standard deviation from average       = 134.7
