It's most likely an OS issue, so upgrading to the latest DB fixpack should
help remedy the error.

Usually system generates more meaningful errors prior to SQL0901 generic
system failure message.  In rare cases it does not, but it really ought to.

Here is a link to APAR SE18099 that might apply (i.e. incompatible host
variable types):

Is it possible a data type for one of the fields has been altered and
program was not modified to match?

Subject: embedded sql halt and sql dump

Has anyone else seen this halt ?
i have no authority at this customer to start an IBM Service call, and can
see already the ptf cume level is one level back. 
However, program has been running for many months. 
OS400 V5R3 ptf level c5207530 and db group 99503 level 6
SQLRPGLE compiled at release V5r2 for prev release V5R1
Very basic  select statement 

(i did cut & paste this select into strsql & it runs fine)
dump values:
SQLCOD  -901
SQLSTT   58004   (in Info Center as "system error") and produced a qsqlsrv
dump report in qezdebug
No indication (I can see) and "what" system error, but joblog (below has
some info). 
I beleive the sql error occurred "after" a record was read, because program
dump was at a statement 
inside this loop         dou       SqlCod     <> *zero   
Program dump does show all field values of selected record as zero and
Pgm was missing a statement like c/exec sql whenever sqlerror go to xxx

processed. Previous messages may indicate        
                                       that there is a problem with the SQL
statement and SQL did not correctly         
                                       diagnose the error. The previous
message identifier was *N. Internal error

See the previous messages to determine  
                                       if there is a problem with the SQL
statement. To view the messages, use the 
                                       DSPJOBLOG command if running
interactively, or the WRKJOB command to view   
                                       the output of a precompile.  An
application program receiving this return   
                                       code may attempt further SQL
statements.  Correct any errors and try the    
                                       request again.
