DB2 Version 7.2 + FixPak 6, Solaris 8 + Workshop

When I connect to database and compile a simplest store procedure, I got the error message:

[IBM][CLI Driver][DB2/SUN] SQL1086C Anoperating system error " Precompilation/Compilation error " occurred.

Check the log file, it show the following contents:

*** BIND /export/home/db2inst1/sqllib/function/routine/sqlproc/SAMPLE/DB2INS01/tmp/P1348810.sqc ***

SQL1086C An operating system error "" occurred.

Where can I check further or any ideas??

Thanks inadvance.
