Re: specks on disk drives

I like IBM's explanation in the Software Knowledge Base (search for mch0601)
<quote>    This is most often due to a programming error.
The from and to program as shown in the job log are the primary suspects. These 
programs may be operating system or user programs. Most of the problems are 
user program problems. One way to cause this is to open a file with a buffer 
that does not match what the program is expecting. The same is true of a 
program that attempts to read or write a record that is longer than the actual 
record in the program-described file.

If the from and to programs are system programs, there may be a software bug. 
If the from and to program is QSQROUTE or some other QSQ module, the error may 
be in the coding of the user or third-party program that is using SQL. This is 
often seen in COBOL programs that have defined arrays that do not fit the 
results coming from SQL.
