Hi,
After a little more than week with half of the servers in the farm
patched, the issue has only appeared in the unpatched servers and I
haven't seen any odd behaviour from the ones patched.
I'm attaching the patch applied for PG11, but it applies cleanly in
master and PG12 too.
Regards,
Raúl Marín.
