My UDB database was ok when I installed FP3 to test things out.  After
installing FP3 the database gives me this message when I try to
connect to it for the first time:

$ db2 connect to c814db
SQL1084C  Shared memory segments cannot be allocated.  SQLSTATE=57019

Since installing FP3 I have backed it out (back to FP2), but the
problem remained.  I've also backed out FP2 with no luck.  This box is
low on RAM but has nothing else running and was working OK.

Please help!

Below is a section of the db2diag.log that might be useful.

Thanks,
Frank
