There seems to be a bug on 10.6.10 with our query killer which is fixed on 10.6.12 (see T330422#8648488)
We need to upgrade our hosts from 10.6.10 to 10.6.12 (high higher priority to those that use query killers) which are:
- db1200
- db1137
- db1111
- db1168
- db1143
- db2178
- db2102
- db2146
- db2180
- db2122
- db2175
- es2022
- es1022
Less priority:
- pc1011
- pc1014
- pc2011
