DB2 - Problem description

Problem IC66577 Status: Closed

INSTANCE DEFUNCT PROCESSES CREATED UPON LOADS

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
This involves loads using file_transfer_cmd causing db2vend 
process to become defunct as follows: 
 
1. We don't wait for completion of userexit in db2vend (we don't 
call wait nor waitpid after fork and exec in sqloexecs). 
2. Neither set its SA_NOCLDWAIT flag nor set SIGCHLD to SIG_IGN 
as the result of resetting SIGCHLD to default with FILE TRANSFER 
COMMAND option in db2load utility.

a child process of db2vend process, so the first condition will
