Hello
We have same problem, seems that restarting solve it...
But this is the n-problems with ORACLE report server...
We had our customers VERY unsatisfied with Reports OTM part...
Does anybody know a way to stabilize this Bulls..t REPORT SERVER

There is a memory configuration that prevent these continuos problems

There is a suggested version better than others (but howevere supported by OTM)
THanks in advance for any suggestion
Regards
