That old chestnut – the weird ace log issue – now has a bug ID ! (CSCso15332). It only appears to happen if the rservers are offline in the original context. Bizarre.
Here is what Cisco has said on the matter:
The customer was using the same syslog host in two contexts, had configured http and https probes in both contexts, and was logging probe failures in both contexts. The rservers in the second context were unavailable when the issue began; later, those rservers became available and the inappropriate logging ceased.
Further Problem Description:
The customer experienced this problem for approximately ten days sproadically on one rserver. Even during that period there were at most a moderate (20 to 30) number of messages a day.
