"Module ... became unblocked" after FR30 upgrade

[Jakob Hirsch]

Hi,

I'm getting lots of this since upgrading from 2.2.9 to 3.0.11:

The only reference I found was for rlm_sql, where the OP was told that
his SQL server is too slow, which is comprehensible. I don't see how
rlm_detail or rlm_preprocess could be too slow, though, especially since
there were merely 10 requests/s at this time.
