Without seeing the other threads its difficult to see what is happening, however there was a bug fix in 1.5 to stop the cache growing out of control. A quick test with 1.5 would help a great deal.

I dont get this problem if I run with LD_ASSUME_KERNEL=2.2.5 setting. But the applications runs very slow( around 50% slower). Does anyone has come accross this problem ?
